It examines factors like population size, density, dispersion patterns, demographics, survivorship curves, and population growth. Communities differ in their species richness, the number of species they contain, and the relative abundance of different species. Instead of counting an entire population, scientists typically study a portion of a population by sampling, which involves counting individuals within a certain area (or volume for aquatic organisms) that is part of their natural habitat. Identify population growth models and factors that affect population growth. The variety and variability of organisms and ecosystems is referred to as biological diversity. Bonded together, they form molecules, molecules form the compounds. The document discusses population ecology, which is the study of populations in relation to their environment.
