Western Ghats have a large number of plant and animal species that are not found anywhere else. Which of the following terms will you use to notify such species? (NEET 2023 Odisha)
Answer: (A) Endemic. Answer: (1) Endemic.
- A.Endemic✓
- B.Vulnerable
- C.Threatened
- D.Keystone
Correct Answer
(A) Endemic
Solution & Explanation
Answer: (1) Endemic. [option A] Solution: Species confined to a particular region and found nowhere else are termed endemic, and a high degree of endemism is a defining feature of biodiversity hotspots such as the Western Ghats. Vulnerable (2) and threatened (3) describe extinction-risk status, not geographic restriction, while a keystone (4) species is one whose role disproportionately affects its ecosystem. NCERT: NCERT Class XII Biology, Ch 13 Biodiversity and Conservation, p.224, lines 35-36: "'biodiversity hotspots' regions with very high levels of species richness and high degree of endemism (that is, species confined to that region and not found anywhere else)."
