Question

Tropical regions show greatest level of species richness becaus
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.
Choase the correct answer from the options given below:

• A. A, C, D and E only
• B. A and B only
• C. A, B and E only
• D. A, B and D only

Answer 1

The Correct Option is A

Tropical regions exhibit the greatest level of species richness due to several factors that contribute to the variety and abundance of species. Let's analyze each option:

• A. Tropical latitudes have remained relatively undisturbed for millions of years, hence more time was available for species diversification. - This statement is correct. The stability of tropical regions over geological time has allowed species to evolve and diversify, increasing richness.
• B. Tropical environments are more seasonal. - This is not true. Tropical environments are typically less seasonal compared to temperate regions, which experience significant seasonal changes.
• C. More solar energy is available in tropics. - Correct. The abundant sunlight in tropical areas fuels photosynthesis, supporting a greater biomass and a wider variety of organisms.
• D. Constant environments promote niche specialization. - Accurate. The stable climate of the tropics allows species to adapt to specific niches, facilitating specialization and diversity.
• E. Tropical environments are constant and predictable. - True. The predictability of tropical climates supports the development and maintenance of diverse ecosystems.

Based on the analysis, the correct answer is:

A, C, D and E only
