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". Community ecology or synecology is the study of the interactions between species in communities on many spatial and temporal scales, including the distribution, structure, abundance ...
The entire array of organisms inhabiting a particular ecosystem is called a community. The number of species making up such a community may vary from a myriad to a single species such as Desulforudis. In a typical ecosystem, plants and other photosynthetic organisms are the producers that provide the food. Ecosystems can be permanent or temporary.
A community is a group of populations of species occupying the same geographical area at the same time. [159] A biological interaction is the effect that a pair of organisms living together in a community have on each other. They can be either of the same species (intraspecific interactions), or of different species (interspecific interactions).
A life form (also spelled life-form or lifeform) is an entity that is living, [1] [2] such as plants , animals , and fungi . It is estimated that more than 99% of all species that ever existed on Earth, amounting to over five billion species, [3] are extinct. [4] [5] Earth is the only celestial body known to harbor life forms. No form of ...
Community (ecology) – Associated populations of species in a given area, or Biocoenosis – Interacting organisms living together in a habitat Species – Basic unit of taxonomic classification, below genus Population – All the organisms of a given species that live in a specified region Organism – Individual living life form
In biology, a colony is composed of two or more conspecific individuals living in close association with, or connected to, one another. This association is usually for mutual benefit such as stronger defense or the ability to attack bigger prey. [1] Colonies can form in various shapes and ways depending on the organism involved.
A plant community is a collection or association [1] [page needed] of plant species within a designated geographical unit, which forms a relatively uniform patch, distinguishable from neighboring patches of different vegetation types. The components of each plant community are influenced by soil type, topography, climate and human disturbance ...
"A community has been viewed as a super organism with integrity analogous to that of cells in an organism. This is the holistic or unitary view of a community, and one championed by Clements (1916). He regarded the community to be a highly integrated unit that operated very much within itself with little interaction with surrounding communities ...
