Directions : In the following questions a statement of assertion (A) ...
Assertion (A) and Reason (R) Overview
The assertion states that the Western Ghats of India are one of the world's biodiversity hotspots. The reason provided indicates that the Western Ghats have greater amphibian diversity compared to the Eastern Ghats.
Understanding the Assertion (A)
- The Western Ghats are recognized as a global biodiversity hotspot due to:
- High levels of endemism (species found nowhere else).
- Significant species richness across various taxa.
- Unique ecosystems influenced by climatic variations.
Evaluating the Reason (R)
- It is true that the Western Ghats exhibit greater amphibian diversity than the Eastern Ghats. Some key points include:
- A higher number of amphibian species have been documented in the Western Ghats.
- The ecological conditions and varied habitats support a rich array of amphibian life.
Relationship Between Assertion and Reason
- Although both the assertion and reason are true, the reason does not directly explain why the Western Ghats are classified as a biodiversity hotspot.
- Biodiversity hotspots are determined by multiple factors beyond just amphibian diversity, such as:
- Overall species richness, including plants, mammals, birds, and insects.
- Levels of endemism across various taxonomic groups.
Conclusion
- Therefore, the correct answer is option 'B': Both assertion (A) and reason (R) are true, but reason (R) is not the correct explanation of assertion (A).
- This highlights the complexity of biodiversity hotspots, which cannot be solely defined by one group of organisms.
