There are 34 biodiversity hotspots in the world.
High level of species richness is a criteria for selection of a biodiversity hotspot.

- If assertion is true but reason is false
- If both assertion and reason are false
The Correct Option is B

Top Questions on Biodiversity and Conservation
- In nature, populations of different species in a habitat do not live in isolation but interact in many ways. Depending on the outcome, these interactions between two species are classified as competition, predation, parasitism, commensalism, amensalism, and mutualism. Through these interactions, trophic energy transfer is facil itated. Some predators help in controlling their prey populations, whereas plants have evolved diverse morphological and chemical defenses against herbivores.

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.
