(C) The second law of thermodynamics states that energy transfer is never $100\%$ efficient,as some energy is always lost as heat. Ecosystems follow this law because energy is lost at each trophic level during transfer.Therefore,the Assertion is true.In a food chain,energy flow is always unidirectional (from producers to consumers). It never flows in the reverse direction.Therefore,the Reason is false.

Assertion: Ecosystems are not exempt from the second law of thermodynamics.
