Question

Tropical regions show greatest level of species richness because -

1. Tropical latitudes have remained relatively undisturbed for millions of years, hence more time was available for species diversification.
2. Tropical environments are more seasonal.
3. More solar energy is available in tropics.
4. Constant environments promote niche specialization.
5. Tropical environments are constant and predictable.

Choose the correct answer form the options given below:

विकल्प

• A, B and E only

• A, B and D only

• A, C, D and E only

• A and B only

Answer 1

A, C, D and E only

Explanation:

For a variety of reasons, tropical areas have the greatest species richness. Because of the long environmental stability in these areas, there has been plenty of opportunity for species diversification. Diverse ecosystems are driven by a high level of solar energy, and niche specialization is encouraged by comparatively stable and predictable conditions. Together, these elements support the remarkable biodiversity found in tropical regions.
