Ecosystems are environments where biotic (living) organisms and abiotic (non-living) components interact together to create a functional, complex network of nutrient and energy cycling. These balanced environments take time, sometimes many years, to develop. During the course of development, species are replaced by other species within the ecosystem, a process known as succession.
