Within an ecosystem:

Question

A Energy flows in one direction only and nutrients are recycled

B Energy is recycled and nutrients flow in one direction only

C Energy and nutrients flow in one direction only

D Energy and nutrients are both recycled

Answer 1

The correct option is: A) Energy flows in one direction only and nutrients are recycled.

This statement reflects the unidirectional flow of energy from the producers to the consumers and eventually to decomposers. The energy is not recycled but lost in the form of heat. On the other hand, the nutrients are recycled continuously within an ecosystem through the biogeochemical cycles.
