Which of the following is not true about the tropics?

 

 

Frequent glaciations in the past occurred in temperate regions but not in tropical regions.

Tropical environments, unlike temperate ones, are less seasonal, relatively more constant and predictable. Such constant environments promote niche specialisation and lead to a greater species diversity and there is more solar energy available in the tropics, which contributes to higher productivity; this in turn might contribute indirectly to greater diversity.
