The interaction between a community of living organisms and the non-living parts of its environment.
The pond becomes an ecosystem when we consider how that community interacts with its non-living surroundings, such as water, light and temperature. Living parts are called biotic; non-living parts are abiotic. An organism's habitat is the place where it lives.

A community of organisms interacting with one another and with the non-living parts of their environment.
To describe the whole ecosystem, include both the community and the non-living environment with which it interacts. Living parts, such as plants, animals and microorganisms, are biotic components. Non-living parts, such as light, water, air, soil and temperature, are abiotic components.

A system of living organisms interacting with one another and with their non-living surroundings.
An ecosystem contains living organisms—its biotic components—and non-living surroundings, or abiotic components, such as air, water and soil. Organisms need materials from those surroundings to build and maintain their bodies. The materials do not move in one direction and disappear: they pass between organisms and the environment repeatedly.

Exam tips

1
Do not claim that high biodiversity prevents all ecosystem change. It generally makes an ecosystem more stable because species are less dependent on any single other species.
2
Keep biodiversity separate from population size: an ecosystem can contain many organisms but still have low biodiversity if they belong to very few species.
3
Do not say that energy is recycled: materials cycle, while energy enters ecosystems mainly as sunlight.
