Question

In the given figure, identify the trophic level having maximum concentration of harmful chemicals.

Options

• T1

• T5

• T4

• T3

Answer 1

T5

Explanation:

The trophic level with the maximum concentration of harmful chemicals is T5. This occurs due to a process called biomagnification (or biological magnification). Because these chemicals are not easily broken down or excreted by organisms, their concentration increases at each successive level of the food chain, reaching the highest levels in top predators.
