Answers. 1  A food chain is the what animal eats what animal. It really should be called a food web because many animals eat many other animals. The food web is a representation of an energy pyramid. An energy pyramid just shows where the energy is going. The sun is at the bottom, then plants and so on. There really are not many differences between them.
A food web differs from a food chain in that it includes all the organisms whose feeding habits are related in some way or another to those of other organisms. In the example above, small animals other than rabbits feed on lettuce and carrots and, in turn, those animals are fed upon by a variety of larger animals.
