NEET Biology question
Each question contains ASSERTION (Assertion) and REASON (Reason). Each question has the 4 choices (a), (b), (c) and (d) out of which ONLY ONE is correct. **Assertion:** Decrease in species diversity occurs as we ascend a high mountain. **Reason:** Decrease in species diversity occurs with increase in altitude due to a rise in temperature.
Answer: (C)
Solution
The Assertion is true: species diversity does decrease as one ascends a high mountain, since higher altitude is associated with harsher, more variable conditions less favourable to diverse life. However, the Reason is false, because temperature actually decreases (not rises)
