The things that an organism interacts with, which can be differentiated into biotic and abiotic components.
Note that environments are not just places, though location nonetheless is an important defining characteristic that helps to differentiate one environment from another.

The scientific discipline of ecology is the study of the interaction of organisms with their environments.
