Question

give reason, floe of energy in food chain is unidirectional​

Answer 1

Answer:

First its flow not floe

Explanation:

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.

Answer 2

Because the energy moves progressively through the various trophic levels and is no longer available to the previous trophic level. The energy captured by autotrophs does not revert back to the solar input.Thus, flow of energy in food chain is always unidirectional.
