- (a) ,(b) above and microbes also living in this natural habitats
Hide Solution
Verified By Collegedunia
The Correct Option is D
Solution and Explanation
An ecologist use the term biodiversity or biological diversity to the variety of life forms and habitats found in defined area. In other words biodiversity can be defined-as the variety of species of all Iiving plant and animals and microbes also living in their natural habitats and the ecological complexes of which they are a part.

Concepts Used:
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.
