What is a community?

In GCSE biology a community is a group of populations living in a habitat at any one time. Populations within a community are constantly interacting with each other, meaning that they are affected by biotic (living) factors such as predation, feeding and competition. We say that populations in the same community are interdependent, so any change in one population will impact other populations.

Communities are also affected by abiotic (non-living) factors in their environment. The living organisms in a community, and their interactions with the living and non-living environment, make up an ecosystem.
