Question

Energy transfer is said to be unidirection where as biochemical transfer is said be cycling. Why?

Answer 1

You will see a process of absorbing energy on earth, take a very simple e.g.

In food chain

plants to herbivores to carnivores & omnivores & top Carnivores

means the energy transfer in food chain is unidirectional.

Biochemical are come in body and back to environment

Oxygen & Nitrogen cycle is a best e.g.

Answer 2

I think the flow of energy is unidirectional from one organism to another in a reduced quantity but decomposition of such animals by decomposers make the cyclic movement of elements (nutrients).


All these takes place between the living organisn and their non- living surroundings.
