Question

Assertion (A): Vulture will always have the least amount of pesticides in a food chain.

Reason (R): Vulture occupies the last trophic level and it gets only 10% of energy of the previous trophic level.

विकल्प

• Both A and R are true, and R is the correct explanation of A.

• Both A and R are true, and R is not the correct explanation of A.

• A is true but R is false.

• A is false but R is true.

Answer 1

A is false but R is true.

Explanation:

The assertion is false because vultures have the highest pesticide concentration due to biomagnification, which occurs when toxins accumulate and rise in concentration as they ascend up a food chain. The reason for this is because vultures are at the highest trophic level, and only around 10% of energy is transported across levels. However, the argument does not explain why the assumption is false; 10% energy transfer is a separate ecological principle.
