Question

Species richness of a habitat can be defined as

• A. total number of individuals of a particular species present per unit area of a given region
• B. total number of species present per unit area of a given region
• C. the area covered by a particular species in a given region
• D. the area covered by all the species in a given region

Answer 1

The correct option is B total number of species present per unit area of a given region

Species diversity refers to the variety of species in a region and is determined by its species richness.

Species richness refers to the total number of species present per unit area of a region.

Thus if we consider two habitats of the same area coverage, the one with a higher number of species will have greater species richness.
