Giving two reasons explain why there is more species biodiversity in tropical latitudes than in temperate ones.

Explanation

A forest in tropical refion like equador has up to 10 times as many species of vascular plants as aforest of equal in temperate region like midivest of the USA Hypothisis for the same are-
(a) Speciation is generally function of time, unlike temperate regions subjected to glaciation, tropic have remained undisturbed.
(b) Tropic environments are less reasonal, more constant and predictable. it promotes in the specialisation and greater species diversity.
(c ) There is more solar energy in tropics where contribute higher productivity.
