Give scientific reasons: There is greater biodiversity in the tropical regions of the world.

(N/A) The reasons for greater biodiversity in the tropical regions of the world are as follows:
$1$. Unlike temperate regions,which have been subjected to frequent glaciation in the past,tropical latitudes have remained relatively undisturbed for millions of years. This has provided a long evolutionary time for species diversification.
$2$. Tropical environments,unlike temperate ones,are less seasonal,relatively more constant,and predictable. Such constant environments promote niche specialization and lead to greater species diversity.
$3$. There is more solar energy available in the tropical region,which induces higher productivity and thus supports greater biodiversity.
