  • D
    Number of individuals decreases from first trophic level to fourth trophic level
✓

Answer

Correct option: C.
Energy content gradually increases from first to fourth trophic level
c
Energy content does not remain trapped permanently in any organism. It is passed on to various trophic levels in food chain.

Hence, energy content gradually decreases from first $\left(T_{1}\right)$ to fourth $\left(T_{4}\right)$ trophic level by following ten percent law proposed by Lindemann.
