Ecosystem and Living Things

Each species confronts the challenges of survival in its own unique fashion. The way in which an organism interacts with other living things and with its physical environment defines that organism’s niche, or role in an ecosystem. Different species in an ecosystem often interact with one another in such a way that over a very long period of time they develop intimate associations and influence each other’s evolution. The species composition of an ecosystem in a given area undergoes orderly changes over time.
