Definition Of Community In An Ecosystem

In its simplest form it refers to groups of organisms in a specific place or time for example the fish community of lake ontario before industrialization.

Definition of community in an ecosystem. An ecosystem comprises both biotic factors and abiotic factors in a particular geographical area. This means that besides the biomass of living organisms that is present we are also concerned with the soil or water that plants and animals happen to be found in and the associated nutrients and resources. Communities consist of a group of different species which partake in direct and indirect biotic. The collection of plants animals and microorganisms in a particular ecosystem is a community.

The levels include an organism the population the community the ecosystem and the biome which all are part of the biosphere. A biotic community also known as a biota or biocoenosis is the group of organisms that live together and interact with each other within an environment or habitat together the biotic community and the physical landscape or abiotic factors make up an ecosystem. Thus an ecosystem can encompass multiple communities. An ecosystem can be defined as all the interacting components of the physical and biological world.

For example a forest of trees and undergrowth plants with animals bacteria and fungi makes up a biological community. In ecology a community is a group or association of populations of two or more different species occupying the same geographical area at the same time also known as a biocoenosis the term community has a variety of uses. An organism s community is part of an ecosystem. A forest grassland pond and estuary are the examples of ecosystems.

Keep in mind that drawing a line around a community or an ecosystem is not a clear matter either. Ecosystem and community are two ecological levels. It differs from an ecosystem which consists of the biological community together with its physical environment.
