The tropics between `23.5^(@) N` to `23.5^(@)S` harbours more species than temperate and polar regions.Enlist the probable reason for Difference in biodiversity between tropical and temperate regions.

Text Solution

Verified by Experts

(i) Tropical have remained undisturbed for millions of years whereas temperate are subjected to frequent gradations.
(ii) Tropical environment is less seasonal, more constant and predictable which promote greater species diversity.
(iii) More solar energy is available in the tropics which contribute to higher productiviey and greater biodiversity.
