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

Answer:

                  Flow of energy in an ecosystem is always unidirectional, i.e., energy flow in one way and isnoncyclic, like                                           As the energy content is decreasing from 1st trophic level to next trophic level and so on, thus the energy cannot pass in reverse direction.
