Measurement of the number of individuals living in a defined space is known as what?

Explanation:
Population density is the measurement of the number of individuals living in a defined space. It is calculated as the number of individuals divided by the area (or volume) they occupy, giving units like people per square kilometer. This concept helps compare how crowded different areas are and tracks changes over time. It’s different from biomass, which is the total mass of living matter; from habitat, which refers to the physical environment where organisms live; and from the hydrologic cycle, which describes the movement of water through the environment. For example, 1000 people in 10 square kilometers equals 100 people per square kilometer.
