Question

The flow of energy is unidirectional whereas the biogeochemical transfer is cyclic explain why

Answer 1

In a food chain, the flow of energy is from one trophic level to another which is used up by the organisms in various physiological processes. The decomposition of the total amount of energy absorbed cannot be reversed. So the flow of energy in a food chain is unidirectional.

Answer 2

Answer:

A large amount of energy is always lost into the atmosphere during its transfer from one level to another. This lost energy cannot be replenished from the atmosphere. Thus, the energy flow is unidirectional. On the other hand, the biogeochemical substances are never lost in the biogeochemical cycle. They are only recycled.
