Question : There is greater biodiversity in tropical /subtropical regions than in temperate region. Explain. |
|
Answer» Solution :Speciation is generally a function of TIME, UNLIKE temperate regions subjected to frequent glaciations in the past, tropical latitudes have remained relatively undisturbed for millions of years and thus, had a long EVOLUTIONARY time for species diversification. 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. There is more solar energy available in the tropics, which contributes to higher productivity, this in turn might contribute indirectly to greater diversity. |
