The Correct Option is B

Solution and Explanation

In tropical region (latitudinal rang of $ 23.5^{\circ}N $ to $ 23.5^{\circ}S $ ), Species diversity is maximum than temperate region. This richness of species is due to higher rain fall (precipitation) throughout the year which in turn result into higher relative humidity, both condition allow to flourish fauna and flora, i.e., abundant evergreen forest with lower group plant like algae and bryophytes.

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.
