Commensalism, in Biology, a relationship between individuals of two species in which one species obtains food or other benefits from the other without either harming or benefiting the latter.

The commensal-the species that benefits from the association-may obtain nutrients, shelter, support, or locomotion from the host species, which is unaffected. The commensal relation is often between a larger host and a smaller commensal. The host organism is essentially unchanged by the interaction, whereas the commensal species may show great morphological adaptation. This relationship can be contrasted with mutualism, in which both species benefit.

This type of relationship is known as commensalism. In commensalism, one species benefits while the other is neither positively nor negatively affected. It is a form of symbiosis where one organism benefits without causing harm or receiving any benefits.

An example is the presence of algae in lichen or intestinal microbes in any animal. This is called symbiosis.


What is symbiosis?

Symbiosis is a close, prolonged association between two (or more) organisms of different species that may, but does not necessarily, benefit each member. The specific biological interactions of symbiosis can be subdivided in three: * Mutualism, where both organisms benefit. * Commensalism, where only one of them benefits, but the other is not affected. * Parasitism, where one benefits and the other organism is harmed.


What describes a symbiosis between organisms?

Symbiosis refers to close interactions between two different species. There are 5 basic forms of symbiosis, three of which are the most common: mutualism where both parties benefit; parasitism where one party benefits and the other is harmed; commensialism where one party benefits and the other is indifferent. There is also amensalism where one party is indifferent and the other is harmed, and synnecrosis where both parties are harmed. These last two cases are more rare than the other three.

An ecological relationship between organisms of two different species that live together in direct contact?
