...204 10/28/15 iLab1: Deforestation 1. Discuss 5 products that come from tropical rain forests. a. Chocolate originates from the cacao plant, which grows in Central and South America. Its cultivation is a forest-friendly source of income for those living in the Amazon. (Larsson) b. Moisturizer has ingredients that originate in the Amazon. These ingredients include the Brazil nut and coconut oil. (Larsson) c. Medicine’s ingredients can come from the Amazon and have the properties to smell great and save lives. Tropical rainforests provide for 70% of the plants that have proven anti-cancer properties. (Tropical Forests, Larsson) d. Home and office products come from the most valuable types of wood only found in tropical rain forests. Though this may lead into deforestation, cutting down these trees. (Tropical Forests) e. Açaí is found in the Amazon, and is known as the super fruit of super foods. It is rich in proteins and is a massive health hit. (Larsson) 2. With clear examples, discuss 5 major causes of deforestation. a. Agricultural expansion (farming) demands come from an increase in consumer product demands. The Trans-Amazon Highway was to be built in the Amazonian basin, but it was a failure. However, the plan was to easily transport wood. (Debjani) b. Shifting cultivation is temporary growth, reliant on the clearing of a given area of a tropical rain forest. Once the cultivation amount is achieved, the area is abandoned. This occurs...

...in Guam’s limestone forests is extremely limited. In order to account the number of species available in comparison to the Panama tropical rainforests, data gathered from of 20x20 plots were recorded. Throughout this study, factors for Guam’s limited species diversity may be generalized but not fully confirmed. Overall the main purpose is to get an idea of what type of species are available in the limestone forests, as well as provide data for researchers to pursue further studies as to why species are so limited here on this island. Introduction Tropical rainforests, along with temperate ones, are the most complex biomes on earth. This is due to the many ecosystems found within them. Although it is assumed that rainforest are fertile with plant species due to nutrient-rich soil, it is not. Most nutrients are either washed away from the soil due to heavy rainfall or recycled through the vegetation. Usually new growth within the forest greatly depends on decomposing organisms, such as bacteria and fungi (Tang et al.2011). Specie diversity varies within these rainforests depending on conditions surrounding and affecting each. Considering that species diversity is one of many crucial elements to nature conservation, thorough studies must be conducted to identify such conditions of limited rainforests. (Primack 1993). Categorized within Tropical forests are karst or limestone forests that consist of endemic plants and trees. Guam’s limestone forests are also the most...

...Dhalladoo October 31, 2015 This lab will discuss four points of Tropical Rain Forest. The first discussions will be on five products that come from tropical rain forest. The second one is five major causes of deforestation which I will give you some clear examples. I also will discuss the third one that cover two reasons why is so difficult especially in the Amazon tropical Forest, and finally the discussion will be on the Water and Carbon Cycle and how deforestation impact bout cycles. First discussion: Five Products that come from the Tropical Rain Forest. One of the products that come from the rain forest is the trees itself, the trees are used for many things example they are cut into logs to shipped to different countries, also the trees can be used for making wood use by the people and tribes who live in the forest its self to build their homes as well as the vines can also be used to make house births and chairs. The second product are plants and leaves. Some of this plants are used for medicine by the tribes and local people. Scientists use this plants for experimenting in the search for the cure of different diseases. One of them is cancer in Australia the scientist found properties for curing cancer and is tested in animals like monkeys but not in humans yet, they are still working on it. Third product that come from tropical rain forest it will be food products, for instants tropical fruits is the papaya or sour-sources, cacao the main ingredient in chocolate...

...The tropical rain forest is a forest of tall trees in a region that is warm all year long. Anywhere between 50 to 260 inches of rain falls a year. The temperature in a rainforest doesn't get higher than 93 degrees or drops below 68 degrees ; average humidity is between 77 and 88%;more often than not rainfall reaches 100 inches a year. There is usually a brief season of less rain. In monsoonal areas, there is a real dry season. Almost all rain forests lie near the equator. Rainforests now cover less than 6% of Earth's land surface. Scientists estimate that more than half of all the world's plant and animal species live in tropical rain forests. Tropical rainforests produce 40% of Earth's oxygen. A tropical rain forest has more kinds of trees...

...Brandi Long Environmental Science-204 July 12, 2012 I-Lab#1 Deforestation Exercise 1 Discuss 5 products that come from tropical rain forests. A lot of the ingrediants that make of medication that is used in today’s world come from tropical rain forests, like Lapacho (Pav D’ arco). This is used for chemotherapy medicine for patients that have cancer. Lapacho has been noted to be beneficial for other conditions, like bacteria, viruses, parasites, arthritis and fungi. In fact, 70% of the plants used for anti-cancer drugs can only be found in the tropical rain forests. About 7% of paper pulp used to produce paper comes from the tropical rain forests. Mahogany and teak wood that is used for making furniture comes from the trees growing in the tropical rain forest. All the passion fruits used in the ingredients for shampoo all come from the tropical forest. Vanillas that are used for cooking and baking are from vanilla seed pods from the vanilla orchid grown in the tropical rain forest. Exercise 2 Discuss 5 major causes of deforestation. As the population grows world-wide, more volume is needed, like our food supply. Farmers will deforestation land to raise cattle, for meat. This would cause some deforestation from the cattle grazing. Workers go and lumber the trees so the wood could be used for materials; like paper. Creating roadways, whether for travel by vehicles and railroads they would need to clear land, the...

...GEO 215 Week 3 DQ 3 How will the deforestation of the Earth’s tropical forests affect the Earth’s temperature or climate? Explain. Response #1 Rainforest grows to large heights and it is important because a growth in the sunlight through the forest canopy can lead to species of the forest not surviving. with the forests getting direct sunlight and over 2 inches of rain an hour, the area is hot and humid. Deforestation is where less heat is absorbed and less moisture is released. The plant life that needs this warm, wet atmosphere will die with more sunlight and less moisture. Deforestation can be related to the growth of drought, flooding and releasing oxygen. Acres of the rainforest is being deforested globally and stored carbon is being released into the atmosphere. The rainforests play a hugh role in the local climate regulation because of the rainforests interaction with the water cycles. The rainforests have an enormous effect on global weather. Rainforests vegetation affect the surface albedo or the surface of the ground absorbing more heat than bare soil. The loss of the rainforest vegetative cover will mean there will be less heat absorption moving on to less moisture being taken up into the atmosphere. The deforested regions may decline the rainfall. Deforestation can affect weather in other parts of the world. There can be a change in the rainfall. The rainforest help generate rainfall over land masses. Response #2 Deforestation affects the climate by escalating...

...you know about atmospheric circulation and seasonal changes in the sun’s orientation to earth to explain the highly seasonal rainfall in the tropical dry forest and tropical savanna biomes. (Hint: Why does the rainy season in these biomes come during the warmer months?) Heating of the earth surface and atmosphere and influences patterns of precipitation the sun heats the air at the equator causing it to expand and rise. This warm moist air cools as it rises. Since cool air holds less water vapor than warm air the water carried by the rising air mass condenses and forms clouds which produce the heavy rain fall associated with the tropical environment. Eventually this equatorial air mass ceases to rise and spreads north and south. The high altitude air is dry since the moisture it once held fell as a tropical rain fall. When the air mass flows north and south it cools which increases its density. It sinks back to the earth’s surface at about 30 latitude and spreads north and south. The air draws moisture from the lands over which it flows and creates deserts in the process. Temperature is plotted on the left vertical axis and precipitation on the right vertical axis. Temperature and precipitation are potted on different scales so 10 C is equivalent to 20 mm of precipitation. Climate diagrams for wet areas such as tropical rain forest compress the precipitation scale for precipitation above 100mm so that 10C is equivalent to 200mm of precipitation. This will change in scale...

...DEFORESTATION Environmental Science with Lab Sabbir Chowdhury November 1, 2015 ILAB 1 Exercise 1: Discuss 5 products that come from tropical rain forests. Tropical rain forest consist of many types of products, because of deforestation many types of plants and products are getting demolished. This is a negative sign for the rainforest because the more deforestation there is the smaller the chance of finding rain forest products. Some of the products which you will find in the rain forest are Pharmaceuticals plants which are very tough to find. Strychnine is a plant which is used for heart disease. Curare is plant used for relaxation for the muscle. Some others products you can find are Guava, Avocado, Coconut Oil. If deforestation continues then there is a high risk chance of finding these products in future (Tropical Rainforest Resources , n.d.). Exercise 2: With clear examples, discuss 5 major causes of deforestation. Major causes of deforestation are human population, logging, agriculture, urbanization, and plantation. There are more than 7 billion population in this world, and to accommodate everyone’s and new born coming to everyday life, we will need more lands and houses to build for them. Logging is another cause of deforestation. All of the wood based industry such as furniture’s, papers etc are need of so many wood supply. Wood is used as a fuel for so many reasons, and this requires the need of chopping down so many trees. Agriculture is one of the major...

...from high latitudes in the direction of low latitudes, and warm air from low latitudes in the direction of high latitudes. As air rises above the surface it moves away near the top of troposphere and moves to the pole region. Advancing toward the pole the air begins to come together at about 30 degrees north and south latitude. Mechanisms that produce high precipitations in the tropics, mechanisms that produce high precipitation at temperate latitudes and mechanisms produce low precipitation in the tropics. Mechanisms that produce high precipitations in the tropics are any product of the condensation of atmospheric water vapor that is pulled down by gravity and deposited on the Earth’s surface. The mechanisms of precipitation include; rain, snow and sleet, it occurs when the atmosphere becomes full with water vapor and then condenses, and precipitates. Trade winds north...

...Rain forests come in two varieties the tropical and the temperate. Areas larger and full of life in a rain forest are the tropics because an abundance of plants and species making its home there. Tropical rain forests are found in Central America, Africa, and Indo Malaysia. Tropical Rain Forest Because tropical rain forests are near the equator, temperatures are 75 to 88 degree Fahrenheit and have 80 inches of rain throughout the year. Barros Colorado Island obtains about 98 inches of rain yearly with a distinctive parch season during the months of December through April with about 12 inches of rain. Compared to any place on earth biodiversity is higher because of the different species present; About 1,185 varieties of plants, 130 kinds of endemics, 650 types of birds, and 93 species of amphibians. The four major layers that towels through the forest is the, Emergent, the canopy, understory, and the forest floor. The Emergent area has the tallest trees called, hardwood, broad-level, and evergreen that grows beyond 200 feet in height and obtain plenty of sunlight. Butterflies, eagles, bats, and monkeys live in the Emergent area. The Canopy section of the forest is the most important layer because of its flat oval shape leaves that roof over into a maze of leaves. Plenty of animals as well snakes, frogs, and toucan birds live here because of its richness in food. The understory has very little sunlight, which is why plants that grow nearly 12 feet in this area have leaves...

...come from Tropical Rain Forest. There are a number of products that we as consumers use all of the time. First there is a product known as guava- a fruit that is grown in the tropical forest that is rich in dietary fiber and vitamin C. Second, Ginger is a plant grown in the tropical rain forest. Ginger is used as a delicacy for culinary purposes, medicine research, and this product from the rain forest of South Asia is often used as a spice. Next, tropical wood is found in both Malaysia and Indonesia. Tropical wood is used to produce furniture in some areas. Paprika is another tropical spice that is made from the ground. Furthermore, the pineapple is a tropical plant that has a sweet flavor, yellowish in color, and low in saturated fats. Next, we have Cayenne Pepper that is grown in Guinea. Cayenne Pepper is used as a cooking spice. For dinner, I had consumed some Raw Kale that was topped with Cayenne Pepper. Last, we have Agave which is natural sweeter nectar from the Agave Plant. Agave serve a few great purposes such as it absorbs slowly into the body so that it does not cause a rapid increase in blood sugar as graduated sugar does. Agave contributes to a sustainable environment in which we do not deplete our natural resources. Agave provides a great taste to breads, toasts, waffles, and pancakes. 2.

...The tropical rainforest is earth’s most complex biome in terms of both structure and species diversity. It begins with optimal growing conditions: abundant precipitation and year round warmth. The tropical rainforest ecosystem is also-called a tropical wet forest or a tropical moist broad-leaf forest. The rain forest is made up of different vegetation. The ecosystem has a significant amount of rain. It rains at least anywhere from 70-80 inches per year. Rainforests are very delicate biomes. With respect to agriculture, a particular weakness is the very thin layer of soil in rainforests. When rainforests are stripped and converted to agricultural land, the soil cannot support sustained agriculture for very long. In time, the soil is blown away and the land becomes desert. The deforestation of rainforests contributes to the extinction and endangering of numerous species. The tropical rainforest ecosystem can be found in places near the equator in the countries of Asia, Australia, Africa, and South America. One example would be the tall trees. The trees grow high to reach more sunlight. The abiotic factors of this rainforest biome are-the amount of water and sunlight, climate, weather and precipitation. These things affect the trees and animals that live there. These are very important because without the right amount of water and sunlight the trees in the rainforest would not be able to grow and would die. These factors also affect the types of plants and animals that can...

...Question 1 Discuss 5 products that come from tropical rain forests. The rain forest provides us with a number of products. First, they provide a lot of food for the global food supply. Second, it provides the world with a lot of medicines. The forest has many plants the hay chemicals in them used to treat diseases like malaria and diabetes. Next, wood is extracted from the forest for the world. Many of the world’s nice timber types like teak and mahogany used in furniture and building are from the rainforest. Furthermore, the rain forests provide the world clothes. The forest has a lot of plants in it that are used in the clothing industry. Finally, the rain forest is home to millions of wildlife. Question 2 With clear examples, discuss 5 major causes of deforestation. There are many causes of deforestation. First, the increasing need for cattle and other animals. The land is needed for grazing for livestock used to provide meat for the world. Second, agriculture moves into the area. Small and big businesses are moving into the forest areas for the fertile soil to produce vital plants and vegetables. Thirdly, the logging industry is a big part of the deforestation. The logging industry is trying to keep up with the world demand for timber. Next, fires have been destroying them. The recent years have shown an increase in forest fires that were caused by nature and man. Finally, the mining industry has been moving into the rain forest. The mining industry is finding more subterranean...

...climates and organisms. In Miller and Levine Biology, 10 biomes are discussed. They are the Tropical Rain Forest, Tropical Dry Forest, Tropical Grassland, the Desert, Temperate Grassland, Temperate Woodland, Temperate Forest, Northwestern Coniferous Forest, Boreal Forest, and the Tundra. They all have a vast amount of differences between all of the biomes, and they will be discussed. Although not discussed in the book, the taiga is the biggest biome. The average temperature of the taiga is 32 degrees fahrenheit with about 12 to 33 inches of precipitation per year. There is little diversity in plant life. A few broad leaf tree species live in the taiga but mostly evergreen trees are the only ones that have adapted to really thrive in this environment. There are some animals that have adapted to live in the cold and snowy environment. A predator called the ermine has a thick coat of dark fur that turns white in the winter. The snowshoe rabbit also has a fur that turns white in the winter. The wolverine is able to mate during ideal conditions by delayed implantation in which they suspend dormant fertilized eggs until the conditions are ideal for bearing their young. Rainforests are the most diverse having more than 15 million species living in the biome. The rainforest biome is sometimes separated into two different biomes. They are referred to as tropical and temperate. The tropical rainforests are located between the Tropic of Cancer and the Tropic of Capricorn. More than...
