Tropical regions show greatest level of species richness because Choose the correct answer from the options given below.
- A, C, D and E only
- A and B only
- A, B and E only
- A, B and D only
Answer
(1) A, C, D and E only

B: Tropical environments are less seasonal, not more seasonal. Incorrect.
C: More solar energy is available in the tropics, which gives higher productivity. Correct.
D and E: Tropical environments are relatively constant and predictable, and such constant environments promote niche specialisation, leading to greater species diversity. Correct.
Hence A, C, D and E are correct.
