Tropics have more species biodiversity than that of the polar regions. The maximum biodiversity in the tropical reason is due to the following reasons :
(i) Prolonged evolutionary time : The tropics have remained undisturbed in the past and therefore evolved more species diversity.
(ii) High productivity : There is more solar energy available in tropics which contributes directly to more productivity, population sizes and indirectly to greater species diversity.
