NEET Botany Biodiversity and Conservation Questions Solved


Where would you expect more species biodiversity - in tropics or in polar regions? Give reasons in support of your answer.

Tropics harbour more species than polar regions.


1. Tropical latitudes have remained relatively undisturbed for million of years and thus had evolutionary time for species diversification.

2. Tropical environments are less seasonal, relatively more constant and predictable . Such constant environments promote nitche specialisation and lead to a greater species diversity.

3. There is more solar energy available in the tropics . This is responsible for higher productivity which indirectly contributes to greater diversity.
