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 chain in the order in which living organisms consume each other in a particlar ecosystem. Whereas a biomass pyramid shows the progression of energy through a food chain â¦ and the amount each trophic level is required to consume.n energy pyramid is like a food chain, because at the top of the pyramid, there is the most energy, and at the bottom there is the least energy. The same goes for a food chai â¦ n, because the producer has 100% of the energy.
