Ecological levels, habitat and niche

Nested diagram showing individual, population, community and ecosystem, with habitat labelled as the place where an organism lives and niche labelled as its role, resources, tolerances and interactions

Ecology looks at how organisms interact with each other and with their environment. The levels build up from an individual to a population, then a community, and finally an ecosystem, which includes the abiotic environment as well as the living community.
