Ecologists use the term herbivory to refer to a +/- interaction in which an organism eats parts of a plant or alga.
is a +/- symbiotic interaction in which one or ganism, the parasite, derives its nourishment from another organism, its host, which is harmed in the process.
Mutualistic symbiosis, or mutualism, is an interspecific in teraction that benefits both species (+/+). nitrogen fixation by bacteria in the root nodules of legumes; the diges tion of cellulose by microorganisms in the digestive systems of termites and ruminant mammals; the exchange of nutri ents in mycorrhizae, associations of fungi and the roots of plants; and photosynthesis by unicellular algae in corals.

An interaction between species that benefits one of the species but neither harms nor helps the other (+10) is called commensalism. Commensal interactions are difficult to document in nature because any close association between species likely affects both species, even if only slightly.
Species can have positive effects (+/+ or 0/+) on the survival and reproduction of other species without necessarily living in the direct and intimate contact of a symbiosis.
