Concept of an Ecosystem

Concept of an ecosystem
An ecosystem is a region with a specific landscape form.
Ex: Forest, Grassland, Desert, Wetland or coastal area.
The nature of ecosystem depends on its geographical features.
Ex: Hills, Mountains, Coastal plains, Rivers, Plains or Islands.
The term “Ecosystem” was coined by A.G.Tansley in 1935. He defined the ecosystem as “the system
resulting from integration of all the living and non-living factors of the environment”.
Ecosystem is the basic functional unit in ecology. Ecosystem development is an autogenic process.
Ecosystem may also be defined as the interaction of biotic and abiotic components of the environment thereby exchanging matter and energy.
