Food chains are sometimes short because(A) only a single species of herbivore feeds on each plantspecies.(B) local extinction of a species causes extinction of the otherspecies in its food chain.(C) most of the energy in a trophic level is lost as energy passesto the next higher level.(D) most producers are inedible.

Energy Flow

Energy flow is the continuous and directional flow of energy through living beings within an ecosystem. All living beings can be segregated into producers and consumers. These producers and consumers can be further divided in a food chain. The term ‘trophic level’ is assigned to each level of the food chain.
