Question

Flow of energy in food chain of an ecosystem is:

Options :- a) Unidirectional b) Bidirectional c) Multidirectional d) None of these

Answer 1

Answer:

Unidirectional

Explanation:

The flow of energy in an ecosystem is always linear that is uni-direction. At each energy step in food chain, the energy received by the organisms is used for its own metabolism and maintenance. The left over energy is passed to next higher trophic level. Thus the energy flow decreases with successive trophic level.
