Biological interaction


Definition : A biointeraction is an interaction intervening in living systems between biocomponents, as biomolecules (proteins : ; lipids ; nucleic acids : carbohydrates).

In ecology

In ecology, 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). These effects may be short-term, like pollination and predation, or long-term; both often strongly influence the evolution of the species involved. A long-term interaction is called a symbiosis. Symbioses range from mutualism, beneficial to both partners, to competition, harmful to both partners.[1] Interactions can be indirect, through intermediaries such as shared resources or common enemies.
