Question

Assertion (A): Biodiversity decreases while moving from lower to higher altitude.

Reason (R): Decrease in species diversity occurs with increase in altitude due to rise in temperature.

विकल्प

• Both assertion (A) and reason (R) are true, and reason is the correct explanation of assertion.

• Both assertion (A) and reason (R) are true, but reason is not the correct explanation of assertion.

• Assertion (A) is true but reason (R) is false.

• Both assertion (A) and reason (R) are false.

Answer 1

Assertion (A) is true but reason (R) is false.

Explanation:

Biodiversity generally decreases with increasing altitude. Temperature falls as altitude increases, rather than rising, so the reason is false.
