Assertion (A): There is more species biodiversity in tropical latitudes than in temperate ones.
Reason (R) : Tropical environments, unlike temperate ones, are less seasonal, relatively more constant and predictable.

Options

A. Both Assertion (A) and reason (R) are true and reason (R) is the correct explanation of Assertion.(A)

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

Answer

A

Explanation

Explanation : Biodiversity (species richness) is highest in tropics because (i) Tropics had more evolutionary time. (ii) Relatively constanten-vironment (less seasonal). (iii) They receive more solar energy which contributes to greater productivity.
