Biodiversity and Conservation

Tropical regions show the 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 the tropics.

D. Constant environments promote niche specialisation.

E. Tropical environments are constant and predictable.

Choose the correct answer from the options given below:

  1. A.A and B only
  2. B.A, B and E only
  3. C.A, B and D only
  4. D.A, C, D and E only✓

Solution

The tropics have had a long undisturbed evolutionary time (A), receive more solar energy that supports higher productivity (C), and have constant, predictable environments that promote niche specialisation (D, E). Tropical environments are less seasonal, so B is false.
