Under the bright sun, he watches fish eating phytoplankton, then a bird catch the fish. Then he sees an Arctic fox slyly catch the bird and eat it. Finally, Allen sees the polar bear he has been looking for, who then hunts and eats the fox. The transfer of energy from the sun, phytoplankton, fish, bird, and fox to the polar bear is called a food chain. A food web is another way to follow the path of energy from the plants all the way up to the top animal, the animal that has no enemies. Since there are many food chains, many of them criss-cross each other and look like a web. For example, another food chain for a polar bear could be sun, grass, hare, fox, and polar bear. Both of these chains help make up a bigger web.
