Question

energy flow in an ecosystem is one way?​

Answer 1

Answer:

The energy that is captured by the producers does not revert back to the Sun and the energy transferred to the herbivores does not come back to the producers. It just keeps on moving to the next trophic level in a unidirectional way. That is why the flow of energy in the food chain is always unidirectional/one way.

Answer 2

Answer:

Energy flows through an ecosystem in only one direction. Energy is passed from organisms at one trophic level or energy level to organisms in the next trophic level. ... Organisms need it for growth, locomotion, heating themselves, and reproduction.
