The intimate living together of two dissimilar organisms in a mutually beneficial relationship.
In biology, the living together of two or more dissimilar organisms. Includes parasitism if only one of the organisms benefit and mutualism if all of the organisms benefit.
A condition in which two organisms exist together and help each other to survive.
In biology, close association of organisms of two different species, usually to their mutual benefit.
An intimate and obligatory association between two different species of organism (symbionts) in which there is mutual aid and benefit. Compare commensal, mutualism, parasite.
The living together in close association of two organisms of different species. If neither organism is harmed, this is called commensalism; if the association is beneficial to both, mutualism; if one is harmed and the other benefits, parasitism.
A profound and enduring bond between individuals belonging to two distinct species.
A relationship between organisms of different species where they live closely together. In mutualism, both organisms benefit and may become so interdependent that they can’t exist separately. There are other types of symbiotic relationships: commensalism, where one organism benefits without harming the other, and parasitism, where one organism (the parasite) benefits at the expense of the other (the host).
