Question

Flow of energy through various trophic levels in an ecosystem is unidirectional and non-cycle. Explain.

Answer 1

The energy from the sun reaches the food chain through the primary producers (plants). This energy is passed on through successive trophic levels in the food chain followis the 10 percent law where in only 10% of the energy is trnasfered from one trophic level to the next successively. So, the movement of energy is only in one direction from lower to higher trophic level.
