(b) Because it is very particular

(c) Because ecosystem is linear

(d) Because energy flows from one trophic level to the next higher one

I had been asked this question during an interview.

I'm obligated to ask this question of Energy Flow in the Ecosystem in portion Ecosystems of Energy Management

Answer 1

Right choice is (d) Because energy flows from one trophic level to the next higher one

To explain I would say: Energy flow is unidirectional because energy flows from one trophic level to next higher one. One more reason is when there is energy flow some energy lost as heat at each step. This is according to 10% energy transfer law.
