What is the polar bear's role in its ecosystem?

Answer 1

Habitat

Though they are excellent swimmers, polar bears spend most of their time atop Arctic sea ice. Sea ice is an ecosystem in itself, supported at its base by plankton and algae at the bottom of the food chain. Polar bears share this habitat with seals, whales, Arctic foxes, birds and even people.

Pr Predator

Polar bears are the primary predator in the marine ecosystem of the Arctic. They mainly hunt seals and the occasional young walrus or whale. Polar bears mostly eats the fats of their prey. Birds, seals, walrus. In times of scarcity, they eat anything available, including fish, reindeer, birds, rodents, eggs, kelp, berries and even garbage.

Answer 2

The Sea Ice. They live on and around the North Pole, and have to provide for their young for two years. The polar bear is the Arctic region's top predator. As such, it indicates how the rest of the animal, specifically marine populations are doing. The polar bears niche is to eat walruses, fishes, and seals.

Answer 3

The polar bears niche is to eat walruses,fishes,and seals. Also to take care of its babies for 2 years.

The niche of the polar bear is an apex predator. They primarily eat seals. However, when the Arctic sea ice melts in summer and they can't hunt seals, polar bears become opportunistic, filling a niche as a scavenger.
The polar bears' niche is to swim, eat fish and seal, and to raise their cubs. The polar bears are specialized predators of the seal.

Answer 4

Grizzly bears are mainly the top of the food chain besides humans they are not other animals prey, grizzly bears have evolved to become omnivores so they eat berries fish roots and many other animals/plants

Answer 5

polar bears live in the northern Arctic.
The polar bear habitat encompass the entire circumpolar Arctic region. Polar bears have adapted to be able to live in the water and on land. Unlike other bear species, the polar bear are excellent swimmers, and have been spotted more than 100 miles away from land or ice. The polar bear habitat is that of the entire Arctic region. They can be found the cold and at times unforgiving land. Polar bears can be found swimming in the frigid oceans waters, or adrift on ice.

The polar bears main habitat is on offshore pack ice, and along costs and island of the Arctic region. Over 40 per cent of all polar bears living today live in Northern Canada, on pack ice and along the shores of the many island there. Polar bears prefer the ice packs to other parts of their habitat because it allows them to remain in close contact with their main food source. Seals. Polar bears will remain in this ice pack habitat all year. They prefer the sea ice over all other places. When summer comes, and the polar regions warm up, the polar bears will travel many miles to remain on the ice, near their food source, seals. Any polar bears that do not stay on the ice when the ice begins to retreat will have to remain on the land, until the ice forms again in the fall.

For the polar bears that's habitat happens to be in the southern most part of the polar region, in Manitoba, Canada on the Hudson Bay, find it difficult to follow the retreating ice and are forced to remain on the land. These polar bears live off fat deposits that they have gained from eating well in the winter. As with the polar bears in the northern region, when the ice pack forms again in the fall, the polar bears return to the frozen sea, to the ice packs.
The polar bear is found in the Arctic Circle and the nearby islands. They can be found in good numbers in Alaska, Norway, Denmark, Russia and Canada. There are smaller populations in the surrounding regions near the Arctic pole. They prefer the Cold Icy areas of the Arctic and thrive in areas where the human intervention is minimal. They are found in good numbers in areas where their primary prey, the Seals mate and nest.
The North Pole, a cold snowy region, is the polar bear's habitat.Polar bears are also found in Northern regions of Canada and Alaska.
Polar bears live in cold habitats mainly in the arctic. If we warm the earth with global warming too much polar bears will die as they live in ice cold conditions.
