What are the abiotic factors a polar bear needs to survive in the tundra?

abiotic factors that affect polar bears are the cold, snow and water. The extreme cold in the Arctic region that the polar bear inhabits means that it has adapted in several ways. The polar bears have grown long, thick fur and have a thick layer of blubber just under the skin. They also have small ears and tails, which reduces the loss of cold through these areas.
