NEET Biology question
**Assertion:** The loss of biologically useful energy as heat with every energy transfer in a food chain is a consequence of the second law of thermodynamics. **Reason:** Energy does not remain trapped permanently in any organism; it is either passed on to a higher trophic level or becomes available to detritivores and decomposers after the organism dies.
Answer: (B)
Solution
Both statements are correct — energy dissipation as heat at every transfer follows the second law of thermodynamics, and energy indeed flows onward (to higher trophic levels or decomposers) rather than being retained
