Tropical region has greater biodiversity than temperate region. Justify the statement with three reasons.

Explanation

(i) Unlike temperate regions subjected to frcqucnt glaciations in the past, tropical latitudes have remained relatively undisturbed for millions of years and thus, had a long evolutionary time for species diversification.
(ii) Tropical environments unlike temperate ones, are less seasonal, relatively more constant and predictable, promotes niche specialization and lead to greater species diversity.
(iii) There is more solar energy available in the tropics, which contribute to higher productivity.
