Document Summary
Ecology is the scientific study of interactions between organisms and their environment. It is the scientific study of interactions that determine the distribution (geographic location) and abundance of organisms. Ecology differs from environmental activism and environmental science (which look at solutions to environmental problems). Ecologists try to explain why organisms are where they are and what makes them successful. Balance of nature natural systems return to their original preferred state after a disturbance. Things are always changing and random perturbations often play an important role in nature. Each species has a distinct role to play in maintaining that balance. There is a lot of redundancy of species and some species can be lost and the outcome won"t change. Some species are a lot more important than others. Different species in an area often respond in different ways to changing conditions. No population can increase in size forever (there are limits).
