Consider the following statements regarding biodiversity hotspots:1. A...
The correct answer is option B: 2 and 3 only.
Explanation:
1. A biodiversity hotspot is a biogeographic region that is both a significant reservoir of biodiversity and is threatened with destruction.
This statement is correct. Biodiversity hotspots are areas that are characterized by a high level of biodiversity, meaning they contain a large number of species, many of which are endemic (found nowhere else). These areas are also under significant threat due to human activities, such as habitat destruction, deforestation, pollution, and climate change.
2. Globally, the total number of biodiversity hotspots has witnessed a decline over the years.
This statement is incorrect. The total number of biodiversity hotspots has not witnessed a decline over the years. In fact, the number has remained relatively stable. The concept of biodiversity hotspots was first introduced by Norman Myers in 1988, and since then, the number has been recognized as 35 globally. These hotspots are distributed across various regions around the world, including tropical rainforests, islands, and Mediterranean ecosystems.
3. The Himalayas and the Western Ghats are the only two biodiversity hotspots in India.
This statement is incorrect. While the Himalayas and the Western Ghats are indeed recognized as biodiversity hotspots in India, they are not the only ones. India is a country rich in biodiversity and has several other regions that qualify as biodiversity hotspots. Some of these include the Indo-Burma region, the Sundaland region, the Western Ghats and Sri Lanka region, and the Eastern Himalayas region. These areas are known for their unique ecosystems and high levels of species diversity.
In conclusion, statement 2 and 3 are not correct. The total number of biodiversity hotspots globally has not witnessed a decline, and the Himalayas and the Western Ghats are not the only two biodiversity hotspots in India.

Consider the following statements regarding biodiversity hotspots:1. A...
A biodiversity hotspot
- It is a biogeographic region that is both a significant reservoir of biodiversity and is threatened with destruction. Hence, Statement 1 is correct.
- These regions have a very high level of species richness (not species evenness) and a high degree of endemism (that is, species confined to that region and not found anywhere else). These hotspots are also regions of accelerated habitat loss.
- Initially, 25 biodiversity hotspots were identified but subsequently, nine more have been added to the list, bringing the total number of biodiversity hotspots in the world to 34. As of today, their number is 35. Hence statement 2 is not correct.
- The biodiversity hotspots hold especially high numbers of endemic species, yet their combined area of remaining habitat covers only 2.3% of the Earth's land surface.
- Each hotspot faces extreme threats and has already lost at least 70% of its original natural vegetation. Over 50% of the world‘s plant species and 42% of all terrestrial vertebrate species are endemic in nature.
- Biodiversity Hotspots in India
- Himalaya
- Includes the entire Indian Himalayan region (and that falling in Pakistan, Tibet, Nepal, Bhutan, China and Myanmar)
- Indo-Burma
- Includes entire North-eastern India, except Assam and Andaman group of Islands (and Myanmar, Thailand, Vietnam, Laos, Cambodia and southern China)
- Sundalands
- Includes Nicobar group of Islands (and Indonesia, Malaysia, Singapore, Brunei, Philippines)
- The Western Ghats and Sri Lanka
- Includes entire Western Ghats (and Sri Lanka)
- Hence statement 3 is not correct.
- Himalaya
