Solution
The correct option is C 0.1J
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 10J. Hence energy at primary consumer level would be 1J (10% of 10J). Similarly, at secondary consumer level, energy present will be 0.1J (10% of 1J).
