What is the Definition of the Ecosystem?

By K Balaji|Updated : November 8th, 2022

The simple definition of the ecosystem is that it is a system of biotic (living) and abiotic (non-living) elements that operate together as a single unit. All living organisms are considered biotic components, whereas non-living elements are considered abiotic components. As a result, an ecosystem science definition includes an ecological assembly made up of diverse populations of organisms that coexist in a specific habitat.

Ecosystem Definition, Types, and Examples

An ecosystem consists of all the living creatures and the physical surroundings in which they interact. They link together with each other via nutrient cycles and energy discharges.

There are 4 types of Terrestrial ecosystems, namely,

  • Forest Ecosystem.
  • Tundra Ecosystem.
  • Desert Ecosystem.
  • Grassland Ecosystem.

In addition, there are two categories of aquatic ecosystems: freshwater and marine. In a grassland ecosystem, a food chain can move from a producer of grass (producer) to consumers like a mouse(primary), a snake(secondary), and a hawk (tertiary).

Ecosystem function is the ability of natural processes and elements to directly or indirectly meet human needs for goods and services. Ecological processes and ecosystem structures are thought of as a subset of ecosystem functions.
