Tropical regions show greatest level of species richness because

A. Tropical latitudes have remained relatively undisturbed for millions of years, hence more time was available for species diversification.

B. Tropical environments are more seasonal.

C. More solar energy is available in tropics.

D. Constant environments promote niche specialization.

E. Tropical environments are constant and predictable.

Choose the correct answer from the options given below:

1. A, B and D only

2. A, C, D and E only

3. A and B only

4. A, B and E only

Best answer

Answer: 2. A, C, D and E only

Key idea: tropics have more species because they are stable, predictable and energy rich.

A (long undisturbed time), C (more solar energy), D (constant environments favour niche specialisation) and E (constant, predictable environment) are valid reasons. B is wrong: tropical environments are less seasonal, not more.
