हिन्दीEcologists have proposed several hypotheses to explain why tropical latitudes harbor higher species richness than temperate regions. Consider the following statements: (A) Tropical regions have remained relatively undisturbed by frequent glaciations for millions of years. (B) Tropical environments exhibit extreme seasonal variations and unpredictable climatic extremes. (C) Tropical environments promote niche specialization through relatively constant and predictable conditions. (D) Higher solar energy availability in tropics contributes to higher productivity. Which of the above statements are correct?
Correct answer · Option 2
(A), (C) and (D) only
Explanation
Statements (A), (C), and (D) are correct. Tropical regions provide a constant and predictable environment free from frequent glaciations, promoting niche specialization and higher species diversity. Statement (B) is incorrect because tropical environments are typically less seasonal and more constant/predictable compared to temperate regions, which experience severe seasonal variations.
