3. Ecosystems
The biosphere consists of the zones of the earth where living things exist. These include the atmosphere, the bodies of water and the surfaces of the earth.
An ecosystem is a smaller unit of the biosphere. It includes the living (biotic) and nonliving (abiotic) features in that space. It is easier to study than the entire biosphere.
A Community is a collection of animal populations that interact within that ecosystem.
Populations of species (organisms, that mate and produce viable, fertile offspring) exist and compete for food, habitat and abiotic materials within the ecosystem.
