What term is used to describe the total number of organisms in a population?

• A. Population Density
• B. Population Size
• C. Species Richness
• D. Demographic Structure

Answer: (B)

The term that describes the total number of organisms in a population is referred to as "Population Size." This refers to the count of individuals within a particular species that inhabit a designated area at a specific time. Understanding population size is crucial in ecology because it helps scientists track how populations grow or decline over time, assess the health of the species, and predict future trends. Population density, while related, specifically measures how many individuals live in a given area and can vary with larger populations. Species richness pertains to the number of different species in a given area, not the total count of individuals. Demographic structure refers to the composition of a population, including age, sex, and other factors, rather than the total number of organisms. Therefore, "Population Size" is the most accurate term for total organism count within a population.
