Question

If 10 joules of energy is available at the producer level, then amount of energy present at the level of secondary consumers is (A) 10 j (B) 1 j (C) 0.1 j (D) 0.01 j

Tardigrade Admin · Accepted Answer

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