they may even vanish from the ecosystem altogether. Similarly‚ over some time interval‚ other species within the community may become more abundant‚ or new species may even invade into the community from adjacent ecosystems. This observed change over time in what is living in a particular ecosystem is "ecological succession". why it occurs Every species has a set of environmental conditions under which it will grow and reproduce most optimally. In a given ecosystem‚ and under that ecosystem’s

Aquatic ecosystem An estuary mouth and coastal waters‚ part of an aquatic ecosystem. An aquatic ecosystem is an ecosystem located in a body of water. Communities of organisms that are dependent on each other and on their environment live in aquatic ecosystems. The two main types of aquatic ecosystems are marine ecosystems and freshwater ecosystems. What is an aquatic ecosystem? Aquatic systems are those that contain plants and animals that predominantly depend on a significant amount of water

Ecosystems at Risk Ecosystems and their functioning What is an ecosystem? Ecology – the science that examines the interactions between organisms and their living (biotic) and non-living (abiotic) environment. Groups of organisms and their biophysical environment interact and exchange matter and energy. Ecosystem – the dynamic complex of plant‚ animal and micro-organism communities and their non-living environment as a functional unit. Ecosystems are dynamic; constantly changing and adapting
