Which of the following is considered a hot-spot of biodiversity in India?
- Western ghats
- Indo-Gangetic plain
- Eastern ghats
- Aravalli hills
The Correct Option is A
Solution and Explanation
The Western Ghats is considered a hot-spot of biodiversity in India. These mountain ranges along the western coast of India are known for their high levels of biodiversity and unique ecosystems. They are home to numerous species of plants and animals, many of which are endemic and not found anywhere else in the world. The Western Ghats have been recognized as a UNESCO World Heritage Site due to their ecological significance.
So, the correct option is (A): Western ghats

Biodiversity and Conservation
The term ‘biodiversity’ is derived from the two words- ‘bios' which means life and ‘diversity’ i.e, differentiation or variation. Edward Wilson, the sociobiologist was the first to popularise the term ‘biodiversity’ in the year 1992. The term implies the occurrence of various plants and animals along with their variants such as biotypes, ecotypes and genes on earth. In our biosphere, the immense diversity or heterogeneity remains not only at the species level but also, at every level of biological organization that ranges from macromolecules in the cells to biomes.
Biodiversity and Conservation is a topic covered under the fifteenth chapter and Unit 5 of NCERT class 12 biology.
