Q. No.Which of the following statements correctly describes biodiversity hotspots, as highlighted in ecological studies?
| 1. | Biodiversity hotspots are regions with moderate species richness, where species are widely distributed across the globe, and they cover less than 5 per cent of the earth’s land area. |
| 2. | Biodiversity hotspots refer to regions that cover a large percentage of the earth’s land area but contain fewer endemic species and experience limited habitat destruction. |
| 3. | Biodiversity hotspots are areas that primarily focus on conserving a few key species and do not contribute significantly to global biodiversity conservation efforts. |
| 4. | Biodiversity hotspots are regions with very high species richness, a high degree of endemism, and accelerated habitat loss. Strict protection of these regions could significantly reduce ongoing mass extinctions. |
