Symbiosis is a close ecological relationship between the individuals of two (or more) different species. Sometimes a symbiotic relationship benefits both species, sometimes one species benefits at the other's expense, and in other cases neither species benefits.
Ecologists use a different term for each type of symbiotic relationship:
Mutualism
-- both species benefit
Commensalism
-- one species benefits, the other is unaffected
Parasitism
-- one species benefits, the other is harmed
Competition
-- neither species benefits
Neutralism
-- both species are unaffected
