Polar Bears Biome

The Polar bear lives in the artic and uses the area’s costal waters and ice sheets. They are well equipped to live in this environment because they have a thick coat which serves as an insulator. They mainly prey on seals but have also been known to consume dead whales. They can grow to be 7.25 to 8 feet tall and can weigh around 900 to 1,600 pounds. Polar bears are a keystone species, if their numbers decrease there is a possibility that the seal populations will increase which could be devastating for crustaceans and fish. They help keep populations in balance.

The polar bear possesses a low, flat skull with high-sitting eyes which is best suited to a semi-aquatic life. This also benefits the Polar bear by enabling them to put their heads into puppy dens or breathing holes.

Polar bears are just one kind of animal you can find on the tundra did you know the tundra is the coldest biome of them all? The climate, producers, and consumers, are all parts that make up the tundra.

and Canada offer, black bears can live in both coniferous and deciduous forests, as well as the open alpine habitats. Basically anywhere near a river or some water source, has plenty of trees, and are able to find food. Black bears usually forage alone, even as young cubs. They will stick together with their mother if there is an abundance of food in one are.

Black bears typically live in either coniferous or deciduous forests. For their food, black bears also like to live near rivers with lots of plants and animals. These habitats range all over North America, including Alaska and North Mexico (American Black Bears, 2015). Black Bears can adapt to their habitats, especially when they are in hot or cold climates. In the different climates, like the hot of Mexico, or the cold of Alaska, their fur coat or color may be significantly darker or lighter.

The Ursus Arctos otherwise known as the grizzly bear lives in North America around Northern Canada, Alaska, Wyoming, Montana, and Idaho. A grizzly bear lives in the wild and hunts for its food such as fish, deer, elk, or any other animal. They live inside of caves for protection from the weather, they will also live under trees or anything that will provide them shelter. I believe that grizzly’s have evolved into animals that can survive in many climates and environments.

America. They also live in Canada and Mexico. Grizzly Bears on the other hand live in an

Polar bears are one of the countless species who are endangered. They were one of the first animals affected by global warming and their population is heavily decreasing. Around 1980, the Arctic was as large as 8 million square kilometres. In 2011, studies show that the Arctic has reduced its size to 4.5 million square kilometers. In the future, will there be anything such as the Arctic? Scientist predict by 2040, only a fringe of ice will remain in Northeast Canada and Northern Greenland. This is known as the Last Ice Area. This matter is mostly taking part in Canada, since; Canada holds more than half the world’s polar bear population. Other affected countries include the U.S. (Alaska), Greenland,

With the ever rising global temperatures, melting ice caps, and constant warnings about global warming, it is no wonder that the animals inhabiting the artic regions around the world are now suffering a decline in their habitat as well as their livelihood. Such is the case with the Polar Bears who may soon be gone in a scant few years.

The Polar Bear are found on the icy coasts that surrounds the North Poles and as far south as Hudson Bay. Around 60%of Polar Bears can be found in Canada with the remainings throughout Greenland, Alaska, Svalbard, and Russia where tend to be close to the ocean across the icy fields. The habitats are affected by human encroachment by hunting , and releasing chemical pollutants into the water.The Polar Bear eats Seals, Walrus, and Seabirds. Polar Bears can live up to 20-30 year. Polar Bears have a lot of fur and their fur is clear, white, or yellow. The Polar Bear is 6.5 ft-8.3ft. they can weigh up to 330lbs -1,322lbs and they can swim up to 25mph.

The polar bear, the largest land carnivore in North America, one of the largest animals in the world and a favorite at zoos worldwide, has, over the years, adapted to its harsh Arctic environment. The appropriately named ‘ursus maritimum’ or sea bear usually lives between 15 and 18 years in the wild and spends most of its life on ice. It is the most recent of the eight bear species. The first polar bear was a brown bear subspecies, with brown bear dimensions and brown bear teeth. The polar bear evolution was rapid due to the small population and extreme pressure to survive. Even today, the polar bear continues to evolve to better adapt to the harsh realities of Arctic life.

For the family of bears, I am focusing on the two most popular species from this family namely brown bears and grizzly bears. Brown bears are found in many continents including Asia, Europe and North America. Brown bears have the broadest scopes of habitat as compared to other bear species. On the other hand, the habitat of grizzly bears ranges from Alaska to Mexico and it can be as far as east and western shores of Hudson Bay. The grizzly bears are listed as threatened in United States and Canada. They are also listed as threatened by the U.S. Fish and Wildlife

The polar bear lives up in the Arctic region where global warming and climate change are melting the ice caps that the bears thrive on. They use the ice as a platform from hunting and rest. The random pocket holes in the ice, where the seals pop up at, is where the polar bear catches its prey. With this reduction of ice, “the abundance of seals, and increases the amount of energy and time needed for hunting, leaving less energy for reproduction” (Endangered Species and Habitats).

From my knowledge I know that polar bears live in very cold environments with snow. In Fact they seem to enjoy it. There was no snow at the zoo of course. Therefore the polar bear seem uninterested in the environment it was in.

Can you imagine going from your warmy, sunshine state to the cold, tundra Artic? The polar bear and the Anglerfish are adapted to the extreme enviornments in which they live in. The polar bear and the anglerfish have characteristics to match each habitat they live in. The polar bear lives where the air, ice, and air intersect. They live most of their lives on sea ice. Where, the temperature an drop as low as 50 degrees Farenheit. On occasion, they might visit land only to build birthing dens for females. The famous polar bear may sound like it hibernates because you must think all bears hibernate, but believe it or not, the polar bear does not! They hunt year round which leaves no time to hibernate. The polar bear is the world's largest carnivore
