An ecosystem is a biological community of interacting organisms and their physical environment.
Ecosystem is a self-sustaining and self-regulatory unit of nature. It includes both abiotic and biotic components.
The abiotic components include the non-living components like water, soil rich in nutrients, temperature, light and other climatic conditions.
Biotic components include living organisms. They include autotrophic components like producers (autotrophs), consumers (heterotrophs) and decomposers (saprotrophs).
Natural ecosystems can be broadly classified as terrestrial and aquatic ecosystems.
Forest, grasslands and desert are examples of terrestrial ecosystems.
Aquatic ecosystems can be further classified into freshwater and marine ecosystems.
Seas and oceans are examples of marine ecosystems.
Freshwater ecosystems are further categorised into lentic and lotic ecosystems.
The lentic ecosystems include the standing or still water bodies. Example: lakes and ponds.
The lotic ecosystem refers to the flowing water bodies. Example: rivers and streams.
