Food Web
A food web is a system of interlocking and interdependent food chains. In every food web energy is lost each time one organism eats another. This makes it so there needs to be more plants supporting less plant eaters. There are more autotrophs than heterotrophs, and more plant eaters than meat eaters. Each level has about 90% less energy available to it because some of the energy is lost as heat at each level.
