Question

Why is the energy flow in the ecosytem not cyclic

Answer 1

Answer:

Energy given out by the organisms as heat is lost to the environment, it does not return to be used by the plants again. ... Thus, 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.

Answer 2

Explanation:

Non-cyclical nature of energy flow

• The energy is passed from one organism to another in a food chain but, unlike water and elements such as carbon and nitrogen, energy does not return in a cycle. Energy give out by organisms is lost to the environment.
