Answer 1

Hint: - Biodiversity refers to the variety of living forms on the earth. It is referred to as the variety of species present in a particular geographical location. Biodiversity of a place is high when that place has enough food, water and mates for the growth of flora and fauna.

Complete Answer: -
There are 36 biodiversity hotspots in the world. There are four hotspots in India. The Himalayas, the Western Ghats, The Indo-Burma region and the Sundarbans.
Let us discuss the given options-
Gangetic plain- It is also known as the North Indian Plain. It is the largest alluvial plain with huge deposits of fertile soil. This region is not considered as the biodiversity hotspot in India.
Trans-Himalayas- This region is very cold and arid. It consists of extensive rocks and glaciers. The region contains wild goats, sheep and the animals that can live in cold environments.
Western Ghats- It is the biodiversity-rich region of India. It is the mountain range that runs parallel to the western coast of the Indian peninsula. It consists of 7402 species of flowering plants, 1814 species of non-flowering plants. It consists of several hundreds of mammals and birds. Several thousand species of insects and fishes are also found here. It also consists of several threatened species.
Central India- Central India is a table land. It does not contain many species.

Hence the correct answer is option C.

1. Pollution.
2. Illegal hunting and poaching.
3. Over- exploitation and commercialisation.
4. Climate change.
5. Habitat change.
