NEET Botany Biodiversity and Conservation Questions Solved

BOARD

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.

Reasons:

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.
