...Polar Bears I did my favorite organism on Polar Bears. I chose this animal because it is very interesting on how they live and how they survive. The temperatures in the Arctic tundra vary from 50 degrees fahrenheit to -37 degrees fahrenheit. The diet of a Polar bear is a variety of different organism that live in the arctic tundra. But one thing the Polar bear likes the most is seals and bearded seals. I think that they eat this as their main source of food because they spend a lot of time in the water and the Polar bear is considered a marine animal. They are also known to eat walrus,beluga, and whale. I find it very interesting that they eat a whale considering how big whales can be. But when they cannot find any of the organism to eat they will go and eat some of the very few species of plants that grow in the arctic Tundra. The population of a polar bear is around 20,000-25,000 polar bears in the world. But one issue that is affecting the population is global warming and that is making the ice break up and warming the ocean and if there is no ice that means that there is no Polar bear....

...Black Bear Black bears are one of the more common species in North America. They live in many different habitats are not picky about what they eat. Their keen sense of smell gives them much information about their environment and foods they eat. The American black bear is considered a threatened species in some areas. In fact they are protected in the states of Louisiana, Texas, and Mississippi. In other areas they are actively hunted and are subject to open "hunting seasons". CHARACTERISTICS Black bear anatomy includes a straight face and flat shoulders. It has ears that are often pointed and a short tail. Fur color can vary from black to chocolate brown with gray combinations. One of the more notable facts about this species is that they are excellent climbers, even when cubs. The black bear is very adaptable. They are quite intelligent and curious. But this smaller bear is very shy and generally avoids confrontations. Records of human attacks are rare. FACTS * Size: Length is about 4 to 7 feet long. Weight is about 200 to 600 pounds. * Reproduction: Mating season vary depending on habitat climate but breeding usually occurs May through August. * Gestation: 60 to 70 days. * Birth: January or early February. * Litter size: 1 to 3 cubs. Baby pairs are common. * Birth Weight: Baby cubs are usually under one pound. * Vocalizations: Grunts, moaning sounds, and growling. * Threats: Loss of habitat, territory fragmentation, changes in environment...

...Today you are going to learn about the Grizzly Bear and its physical characteristics, behavior, diet and eating habits, reproduction, and it’ conservation and research. I chose this animal because it is ferocious and I’ve heard awesome things about it. I learned fascinating things about it throughout this research but what I liked more was their diet. So first you will learn its physical description. PHYSICAL CHARACTERISTICS The Grizzly Bear is the largest of the eight bear species. They are covered with a heavy, shaggy fur. The Grizzly Bear is brown but not all are brown. They can be black, cinnamon, red, blond, or a mix of these colors. You can tell the difference between black bears and brown bears (Grizzly Bear) by the muscular hump Grizzly Bears have between their shoulders. They also have large, strong, and slightly covered front claws. These claws can reach more than 4 inches long (10 cm)! Finally, Grizzly Bears have a heavy body with strong muscular legs. However, it’s also a fast animal and it can reach up to 35 miles (56 km) per hour. BEHAVIOR A lot of the Grizzly Bear’s behavior involves with humans and the bear’s cubs. The mother only attacks when she feels that her or her cubs are...

...SPECIES- Ursus Maritimus, Polar Bear, lord of the Arctic. Lives in an area of five million square miles of snow and ice. From Siberia to Alaska and across Canada, Greenland and the Islands north of Norway, he is the master of all living things except man. It lives in the brutal cold, ice, and snow. The temperature can plunge down frequently to -40 degrees and sometimes even lower but that does not bother the polar bear because of its color-less skin and layer of insulation fat. Its range extending around the northern polar region. Necessities of Life-The polar bear eats mostly seals which he has to hunt. His trick is to wait by a breathing in the ice and when a seal comes up by that breathing hole, he grabs it so fast it knocks it unconscious and then he eats it. Other pray is a walrus calf or a musk ox stuck in snow, birds, eggs, fish, and dead whales. And sometimes in the summer it eats berries and grass. The polar bear has no water to drink so it only eats the skin and blubber, avoiding the meat. So by eating the blubber and leaving the meat the male bear is helping keep his body in balance with the surrounding environment. The bear would usually stay in a den or bury it self in the snow to avoid the suns ultra violent rays. Usually the pregnant female polar bear stays in the den.Food Chain-The polar bear finds its way on the top of its food chain. No predator on earth approaches the bear in size. The polar bear towers over everything else in his food chain. The...

...safari, jungle, and arctic. In the arctic, some animals that could be found there include narwhals, polar bear, arctic fox, snowy owl, and artic hare. Most animals from the artic have a warm coat of fur, which helps them survive in these harsh conditions. Narwhals are wale like creatures that have horns on their head, which are actually two teeth that form a tusk. Narwhals have a hide that keeps them warm when in the artic water. Polar bears dig out large caves out of snow to have their cubs in. Polar bears usually have only two cubs, and only come out in the spring. Polar bears usually eat seals, waiting under the ice breathing from holes in the ice. Baby polar bears usually starve before their third birthday; other polar bears often die from oil spills and melting ice. In the safari, some animals that could be found are, zebras, crocodiles, African elephants, and rhinos. These animals live in some warmer climates and have adapted for survival. Zebras have any natural predators such as loins, spotted hyenas, leopards, and cheetahs. Zebras prefer to eat short grass, but will eat tall grass if needed. Zebras are more likely to have a chance to escape predators if in a herd, rather than if alone. Crocodiles are usually more aggressive than their relatives, alligators. Small crocodiles usually feed on fish and aquatic animals, while larger ones eat mammals and birds. African elephants are the largest land animal on earth, weighing from 5,000 to 14,000 pounds...

...Jered Duda Professor Joseph Wolcott English 110 4/3/13 Grizzly Bear Diets The grizzly bear is a subspecies of the brown bear; which generally lives in the uplands of western North America which crossed to Alaska from eastern Russia 100,000 years ago. In 1815, the grizzly formally got his name due to the color of its grizzled grey fur. Biologist John Muir once said that these bears “eat everything but granite.” The eating habits of these bears are pretty extreme and are known to be quite the scavengers. Food sources vary in availability from year to year, and from season to season. Grizzlies move throughout their habitat looking for foods available at that time of year. The availability of many foods is known to the bears by Season and the bears move to these areas based on their experience. In this way, the general seasonal distribution. The three main seasons in which grizzly bears have an extensive diet are Spring, Summer, and Fall (Grizzly Bears). From late March to May, Grizzlies arise from their dens, when adolescent vegetation begins to grow. Within early spring, bears move to lower terrain, away from the snow, to feed on this vegetation. Common spring food sources include ants, grasses, dandelion, clover, and other plants. The Grizzly diet consists with a significant amount of ungulate or hooved animals like elk and bison. Grizzly bears also dig up caches of nuts and pine seeds, stashed by pocket gophers and red squirrels from the previous fall. These inspiring giants...

...behavior and their prey have their own technique on how to Lessing there changes of being eaten. Our textbook defines optimal foraging as the most efficient way for an animal to obtain food. You would think that animals just eat whatever they see and what’s available but this hypothesis is absolutely wrong. According to Darrell Ray, an American Biology teacher human also go through a phase of optimal behavior. Darrell did an experiment with his general ecology class involving a plate of cookies and broccoli. In his experiment he polled how many students would choose a cookie over broccoli. At the end of his experiment he asked his students why did the majority pick cookies over broccoli. There response was because of the taste. Optimal foraging theory suggests a different answer, and it lies in the economic principle of profitability.” Fats and sugars do taste good, as the students noted, but sugars have the added benefit of providing a rapidly available energy boost, while fats have high caloric density. () Grizzly bears are used in the textbook to illustrate optimal foraging in animals. Grizzly bears are characteristic as being a generalist species. According to North American Animals, Grizzly bears are omnivorous and will eat nearly any nutritious foods which include...

...amounts of photosynthesis and growth in plants, permitting animals to have an uninterrupted stock of rations. The consistency in temperature is also a stimulus. Animals do not have to acclimatize to the changing seasons. These animals are provided the opportunity to become familiarized with their ecosystem in methods that are not possible in any other biome. Water also formulates variety (Elizabeth Anne Viau, 2000). Food Web Design: The Temperate Forest: (Elizabeth Anne Viau, 2000).

...The coniferous forest is located in Canada, Europe, Asia, and the United States. The temperature ranges from -40 Celsius to 20 Celsius. Average summer temperature is 10 Celsius. Yearly precipitation varies from 30 to 90 centimeters per year. Coniferous forest regions have cold, long, snowy winters, and warm, humid summers. They have well-defined seasons, and at least four to six frost-free months. There are two types of Coniferous forests: 1. Open, lichen woodland, which has trees, spaced far apart with lichen growing between them. 2. Closed forests, which have trees very close together and a shaded, moss-covered forest floor. The major aquatic zones of the coniferous forest are marine, freshwater, and brackish. The average salinity of marine is 3%, freshwater 1% or less, and brackish mixture of salt and fresh. Clear-cut logging is the biggest threat to the Coniferous forest. Replanting after logging leads to single-species conifer monocultures. Clear cutting accelerates soil erosion, degrades wildlife habitat and leads to the loss of biodiversity. The land is being cleared for ski slopes, landfills, housing, and new roads. In Canada, one acre of forest is cut every 12.9 seconds! Mining operations is another threat to the Coniferous forests because of the chemicals used in mining and the silt released by mining. Road construction destroys the forest and also acts as a barrier to wildlife. Roads isolate populations of species from feeding grounds, natural migration routes and...

...Not many people know that over 15 animals have gone extinct and over 700 are struggling to stay alive all because of human repercussions. Climate change is real, and it is damaging many different aspects of the food chain. Some animals caught in this mess include; Snowshoe Hares, Polar Bears, and the Harlequin Frog species. During the winter, Snowshoe Hares turn white to blend in with the snow in hopes of hiding from predators. This works great until the effects of climate change kick in. When humans burn fossil fuels, they release various greenhouse gases, like carbon dioxide, which get trapped in Earth’s atmosphere because of the “greenhouse effect.” This warms up the Earth and melts the snow before the Snowshoe Hares have time to change...

...species eventually go extinct. There are different variations of severity of the list. Polar bears are on the endangered species list due to global warming. Panthers are on the list due to humans hunting and killing them. Polar bears and panthers are endangered species. Habitat Polar bears may be found, “in the U.S.(Alaska), Norway, Canada, Russia, and Greenland on numerous frozen seas and bays” (Alongi 1). They can be found all across the arctic. They spend a majority of their lives on water or frozen sea ice caps. The polar bears rarely touch solid ground in the short arctic summer. The polar bears depend on the sea ice to hunt and store energy for the summer, but the ice is melting earlier and freezing later. Their habitat is not the same as it used to be. Panthers live in forests, swamps, and prairies, and they are territorial animals who travel hundreds of miles within home range. “Destruction, degradation and fragmentation of habitat are the greatest threats to panther survival” (Threats to Florida Panthers 1). Panthers prefer warm climates over cold climates. More panthers are being lost every year due to humans hunting them, global warming, and pollution. The panthers’ status will continue to go down unless we stop killing them and...

...Camels Camels are herbivores; they eat desert vegetation, such as grasses, herbs, and leaves. How do camels adapt to their environment? Camels have many adaptations that allow them to live successfully in desert conditions. Deserts are hot and dry. Winds blow sand all around, so a camel has long eyelashes. It has nostrils that can open and close. Why do camels have long eyelashes? The long eyelashes keep sand out of the camel's eyes. Thick eyebrows shield the eyes from the desert sun. Why does a camel have nostrils which can close? A camels nostrils can close so it doesn't get sand up its nose. Other Adaptations: 1. A camel can go a week or more without water, and they can last for several months without food. They can drink up to 32 gallons (46 litres) of water at one drinking session! 2. Camels store fat in the hump, not water. The fat can be metabolised for energy. 3. Unlike most mammals, a healthy camel's body temperature fluctuates (changes) throughout the day from 34°C to 41.7°C (93°F-107°F.) This allows the camel to conserve water by not sweating as the environmental temperature rises. 4. Camels feet are wide so they can walk on sand more easily. Their huge feet help them to walk on sand without sinking into it. 5. Camels have thick lips so they can eat the prickly desert plants with out feeling pain. 6. The colour of their bodies helps them to blend into their environment. 7. Camel's ears are covered with hair, even on the inside. The hair helps keep...
