Assertion: The consequence of the second law of thermodynamics is the loss of biologically useful energy as heat with every energy transfer in a food chain.

Reason: Energy does not permanently remain trapped in any organism, it is either passed on to a higher trophic level or becomes available to detrivores and decomposers after the organism dies.

View answer and explanation

Correct option: B

If both assertion and reason are true but reason is not the correct explanation of assertion

Option B is correct because both the assertion and the reason are true, but the reason does not directly explain why energy is lost as heat (second law of thermodynamics). The second law is about entropy increase, not just energy transfer.
