The 2005 and 2010 droughts induced more frequent fires and reduced surface runoff for the region. The Amazon also went from being a global net carbon sink to a source of global net carbon during the drought years. In general, the region also experiences more frequent smaller droughts because the land-use changes have disturbed the region’s hydrological cycle. The forest can no longer evapotranspire effectively because the albedo

The respiratory system role is to allow the exchange of gases oxygen and carbon dioxide between the atmospheric air, blood and tissue cells. It also helps adjust the pH of body fluids. “In addition to gas exchange the respiratory system also plays a role in receptors for the sense of smell, filters inspired air, produces sounds and rids the body of some water and heat in exhaled air”. (Tortora and Derrickson 2006 Pg 918) The most important function of the respiratory system is to supply the blood

1 Tropical Rainforest Unit 1 Individual Project Rosella Fyffe Jane Knapp 3-31-2013 2 Introduction I will be discussing the Tropical Rainforest, and writing about the abiotic components, carbon cycle, nitrogen cycle, and the ecosystem function and structure. Also discussing the disturbance and how natural can bounce back after these types of disturbance. 3 Tropical Rainforest The ecosystem of the Tropical Rainforest is a community of living organisms such as plants, animals

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

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

stages are glycosis, cirtric acid cycle, electron transport. • What is the role of glycolysis? Include the reactants and the products. Where does it occur? the role is to split sugars. Reactants are; food “sugars”. Products are; NADH produced, and is the first stage of cellular respiration • What is the role of the citric acid cycle? Include the reactants and the products. Where does it occur? this begins after two molecules of three carbon sugar produced in glycosis is

greenhouse gases. Primary greenhouse gases include water vapor, carbon dioxide, methane, nitrous oxide, and ozone . Carbon dioxide, as well as other greenhouse gases, is a very important factor in the vital cycles which sustain life on this planet, plants use carbon dioxide in photosynthesis and release oxygen necessary to maintain the lives of animal species, who through exhaling return carbon dioxide in atmosphere, completing the cycle .Greenhouse effect is a natural process which made life on Earth

oxidation the triglycerides are broken down into small units consisting of two carbon atoms and they are generated into acetyl CoA. NADH and FADH2 are created during beta oxidation and funneled into the electron transport chain. The acetyl CoA enters the citric acid cycle where NADH and FADH2 are also made and transported to the electron transport chain. The NADH and FADH2 from beta oxidation and the citric acid cycle are used to make ATP which is used for energy in the body’s cells. (O’Malley,

The Hydrologic cycle, more commonly known as the water cycle, is the movement of water between the Earth’s oceans, atmosphere, and land. There is continuous evaporation of water; uptake of water vapor into the atmosphere; precipitation onto the ocean and land surfaces; and the net atmospheric transport of water from land areas to the ocean. Essentially, the water cycle is the means of how the Earth’s constant supply of water is being recycled. It is imperative that this cycle exists, so that water
