A population is a group of one species living in an environment. A community is a collection of these populations, and an ecosystem is the interactions of this community and the environment (biotic and abiotic factors).

The number of different organisms in an ecosystem is called its biodiversity. Biodiversity encompasses the variety of species, genetic diversity within those species, and the diversity of ecosystems in a given area.
The number of organisms living in a community is a population. The number of different organisms living together in a community, is the community's biodiversity.
The number of different species of organisms in an ecosystem is called biodiversity. Biodiversity is important to ecosystems in case one species dies off.
Homeostasis in an ecosystem refers to the balance and stability of biological and physical factors within the environment. This balance is maintained through interactions between living organisms and their environment, helping to regulate variables like temperature, nutrient levels, and population sizes. When disturbances occur, ecosystems can demonstrate resilience by adapting and self-regulating to return to a state of equilibrium.

Population size is a variable affected by the number of organisms present in a given area. As the number of organisms in an area increases or decreases, the population size of that species will also change accordingly. This variable is essential for studying dynamics within ecosystems and understanding the impact of various factors on the population.
The ecosystem has a complicated series of interactions.
Living things interact in a number of ways. They have symbiotic relationships that can either hurt or be good for the organisms. Most organisms also produce products that other organisms need.
