Question

Assertion : Biodiversity hotspots are the regions which possess high levels of species richness, high degree of endemism and no loss to habitats.
Reason: Total number of biodiversity hotspots in the world is 32 with two of these hotspots found in India.
А. Both Assertion and Reason are correct and Reason is the correct explanation for Assertion
B. Both Assertion and Reason are correct but Reason is not the correct explanation for Assertion
C. Assertion is correct but Reason is incorrect
D Both Assertion and Reason are incorrect

Answer 1

Hint: Biodiversity is defined as the collection of the local flora and fauna. India has always been listed on the list of the richest countries in the world for its biodiversity. Biodiversity is the diversity and richness of life on Earth.

Complete answer:
Now let us first look at the assertion given in the question:
Biodiversity hotspots are the regions which possess high levels of species richness, high degree of endemism and no loss to habitats.
The Biodiversity Hotspot is defined as a biogeographical area that is both a major source of biodiversity and is threatened with destruction. In general, the word biodiversity hotspot is connected to 25 high biodiversity areas of the planet that have lost at least 70% of their original habitat.
Biodiversity is defined as the abundance of living organisms from all types, including land, marine and other aquatic habitats and ecological complexes, including diversity between plants, species, and ecosystems. so does the biodiversity hotspots , so biodiversity hotspots contain different kinds of species.
Biodiversity can also lead to habitat loss. thus the given assertion is not correct.

Let us now look at the reason given in the question:
Total number of biodiversity hotspots in the world is 32 with two of these hotspots found in India.
A total of 34 biodiversity hotspots in the world has been observed till date by Norman Myers and four of them are located in India.
thus, reason given is not correct

Hence, the correct answer is option (D)

Note: Biodiversity hotspots are termed as the regions with a significantly high level of flora and fauna that are threatened by human intervention and activities. A hotspot is referred to as a natural habitat that has at least more than 0.5% of total vascular plants as endemic species and is under threat due to human activities.
