Question

Flow of energy in a food chain is unidirectional give reason 0

Answer 1

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.

Explanation:

☞During the transfer of energy through successive trophic levels in an ecosystem, there is a loss of energy all along the path.

Answer 2

Answer:

In a food chain, the energymoves progressively through the various trophic levels' It is no longer available to the previous level (autotrophs) and the energy captured by the autotrophs does not go back to the solar input. Hence, the flow of energy isunidirectional.
