Which statement is NOT correct regarding the food chain?

The correct answer is Option (4) - In food chain, energy level increases from lower trophic level to higher trophic level.

The statement that is NOT correct regarding the food chain is:

In the food chain, energy level increases from a lower trophic level to a higher trophic level.

Explanation:

In a food chain, energy is transferred from one trophic level to the next, but the energy available decreases as it moves up the chain. This is known as the "trophic pyramid" or "energy pyramid," where each level represents a trophic level. The correct understanding is that energy decreases from lower to higher trophic levels due to energy loss through metabolic processes and heat production.

The correct sequence is:

• Producers (plants) → Primary consumers (herbivores) → Secondary consumers (carnivores) → Tertiary consumers (higher-level carnivores)

So, the energy flow is unidirectional, and each trophic level receives less energy than the one before it.
