Edexcel A-level BiologyThe Nature of EcosystemsLesson 3 of 39

A population is a group of organisms of the same species living in the same area at the same time, which can interbreed. A community is all the populations of different species living and interacting in the same area at the same time.

For example, in a pond the frogs form one population, the water lilies another and the water fleas another. Together with all the other populations of plants, animals, fungi and microorganisms in the pond, they make up the pond community. The community plus the abiotic environment is the ecosystem.
