If 10 joules of energy is available at the producer level, then amount of energy present at the level of secondary consumer is

Options

A. 10J
B. 1J
C. 0.1J
D. 0.01J.

Answer

C

Explanation

Only 10 % of energy is transferred from one trophic level to the next trophic level of a food chain (ten percent law, given by Linderman). In present case, energy available at producer level is 10 J. Hence energy at primary consumer level would be 1 H (10% of 10 J). Similarly, at secondary consumer level, energy present will be 0.1 J (100 % of 1 J).
