Question

Question 8
In an ecosystem, the 10% of the energy available to the next trophic level is in the form of

(a) heat energy
(b) light energy
(c) chemical energy
(d) mechanical energy

Answer 1

Option (c) is correct.
The amount of energy at each trophic level decreases as it moves through an ecosystem. As little as 10 percent of the energy at any trophic level is transferred to the next level; the rest is lost largely through metabolic processes as heat. Plants store chemical energy and the same is transferred to various trophic levels.
