Answer

India hosts 4 biodiversity hotspots:the Himalayas, the Western Ghats, the Indo-Burma region and the Sundaland (Includes Nicobar group of Islands). These hotspots have numerous endemic species.

Answer

Introduction:
India is known for its rich and diverse biodiversity, with numerous unique species found in various parts of the country. To conserve and protect these biodiversity hotspots, the concept of hotspots was introduced. Hotspots are areas that are exceptionally rich in biodiversity but also face significant threats. In this context, the question asks about the number of hotspots that cover India's high biodiversity regions.

Explanation:
The correct answer is option 'B,' which states that there are three hotspots covering India's high biodiversity regions. Let's delve into the details and understand why this is the correct answer:

1. Biodiversity Hotspots:
Biodiversity hotspots are biogeographic regions that possess a significant concentration of endemic species and have undergone extensive habitat loss. These hotspots are considered crucial for conservation efforts as they support a large number of species, many of which are found nowhere else on Earth.

2. Criteria for a Biodiversity Hotspot:
To be classified as a biodiversity hotspot, an area must meet two main criteria:
a) It must have at least 1,500 species of vascular plants (> 0.5% of the world's total) as endemics.
b) It must have lost at least 70% of its original habitat.

3. Number of Hotspots in India:
India is home to several high biodiversity regions, but specifically, there are three hotspots that cover these areas. These hotspots are:
a) Western Ghats: The Western Ghats is a mountain range that runs parallel to the western coast of India. It is known for its rich biodiversity, with numerous endemic species of plants, birds, mammals, and amphibians. The Western Ghats hotspot covers parts of the states of Kerala, Tamil Nadu, Karnataka, Goa, and Maharashtra.

b) Eastern Himalayas: The Eastern Himalayas is another hotspot that covers the eastern part of the Himalayan range. It spans across the states of Arunachal Pradesh, Assam, Sikkim, and parts of Bhutan, Nepal, and Myanmar. This region is known for its diverse flora and fauna, including several rare and endangered species.

c) Indo-Burma: The Indo-Burma hotspot covers northeastern India, along with parts of Myanmar, Thailand, Laos, Cambodia, and Vietnam. It is characterized by its rich tropical forests and is home to a wide range of unique species, including several endemic ones.

Conclusion:
In conclusion, India has three hotspots that cover its high biodiversity regions: the Western Ghats, Eastern Himalayas, and Indo-Burma. These hotspots are of great ecological importance and require conservation efforts to protect their unique species and habitats.
