Polar bears are carnivores, and their staple food is seals, mainly ringed seals, because these seals are widely distributed in the Arctic, and even the Arctic is where they live. Polar bears are the top predators in the Arctic. The remains of seal prey that have not been eaten by polar bears may be an important food source for young, inexperienced polar bears and arctic foxes.

Polar bears digest fat more efficiently than protein. Polar bears are large compared to other bear species, a result of their energy-rich diet. Polar bears are large compared to other ursids, a result of their energy-rich diet. Although birds, fish, vegetation, and kelp are locally available during the ice-free season, polar bears are unlikely to obtain adequate nutrition if they survive on a land-based diet.

Polar bear habitat

Polar bear is an animal that can survive in harsh environments. Its active range is mainly in the sea areas with floating ice near the Arctic Ocean. The preferred habitat is the ice floes of the Arctic Ocean. Ice edges and pressure ridges where breakup and refreezing occur provide the best hunting grounds. As the ice melts and freezes, polar bears will travel as much as 1,000 kilometers north and south.

In the summer, they may remain on islands or coastlines with fixed ice, drift on ice currents or become trapped on land, where polar bears are forced to endure warm weather. Live in areas with many caves. Winter burrows can reach depths reaching the permafrost. The nest chamber has plenty of grass to keep it warm.
