Answer 2

Solution:

Species richness is defined as the number of species represented in a specific region, landscape, or ecological community.

Explanation:

Measurement of biodiversity can be done in two ways:

• Species richness  
• Species evenness

It includes alpha, beta, and gamma diversity.

Alpha diversity is the diversity of a particular area
