Question

Solution of why is the flow of energy in an ecosyste unidirectional

Answer 1

The solar energy captured by the plane does not revert back to the sun. The energy that goes to the secondary consumers does not go back to the primary consumer and the same applies to all graphic levels. Therefore energy flow did unidirectional.

Answer 2

Answer:

The flow of energy in the ecosystem is said to be unidirectional because the energy lost as heat from the living organisms of a food chain cannot be reused by plants in photosynthesis. During the transfer of energy through successive trophic levels in an ecosystem, there is a loss of energy all along the path.
