Final answer:
Density, dispersion, range, and growth rate describe characteristics of the population level of ecological organization.
Step-by-step explanation:
The characteristics of density, dispersion, range, and growth rate all describe the population level of ecological organization. Population density refers to the number of individuals within a specific area or volume, dispersion describes the spacing of individuals within a population, range refers to the geographic area in which a species can be found, and growth rate pertains to the rate at which a population increases or decreases over time.
