The correct answer to the question "Counting the number of species in a habitat is a measure of" is species richness.

Explanation:

Species richness refers to the number of different species represented in a given ecological community, habitat, or area. It is an important aspect of biodiversity, as it indicates the variety of life within a particular ecosystem.

• Species Succession: This refers to the process by which ecosystems change and develop over time, often involving a series of species that dominate initially and are replaced by others.
• Biomass: This term refers to the total mass of living matter in a given area, which does not directly relate to the number of species.
• Net Primary Production: This is the rate at which all the autotrophs (like plants) in an ecosystem produce net useful chemical energy, again not directly measuring species count.

In summary, when we count the number of different species in a habitat, we are measuring species richness, a key indicator of ecosystem health and diversity.
