Energy moves from one trophic level to another as organisms feed on one another.
Explanation:
Energy flows from one trophic level to another in a food chain. according to the ten percent law, only ten percent of the total energy passes onto the next trophic level. While studying the energy flow model two aspects should be taken under consideration. Firstly, the flow of energy is unidirectional and passes on from autotrophs to primary consumer and then secontary, tertiary so on. Secondly the amount of energy decreases at succesive trophic level.
