Answer 2

Explanation:

Polar bears live in the Arctic where the air and water temperatures are very cold. They have special adaptations, or features that help them live in that habitat, like webbed feet, a layer of fat, fur that helps them blend in and dry off, and black skin to absorb the sun's heat.
