Question

What is the movement of energy towards the higher trophic levels and its distribution and loss as heat to the lower trophic levels in the environment?

(a) Multi-directional

(b) Bi-directional

(c) Uni-directional

(d) No direction

The question was posed to me in an online quiz.

This is a very interesting question from Ecosystem topic in division Ecosystem of Biology – Class 12

Answer 1

Correct choice is (c) Uni-directional

To explain I would say: The movement of energy from the higher trophic levels and its distribution and loss as heat to the lower trophic levels in the environment is unidirectional. It means the energy moves in one direction only that is from higher to the lower-most level.
