Exploring Habitats and Food Webs

The video explores the concept of habitats, using a polar bear in the desert as an example of an animal in an unsuitable environment. It explains how habitats provide food, water, shelter, and space, and introduces the idea of food chains and food webs. The video compares food webs in different habitats, such as forests and the Arctic, highlighting the unique adaptations animals have to survive in their environments.
