Symbiosis is an ecological relationship between two species that live in close proximity to each other. Organisms in symbiotic relationships have evolved to exploit a unique niche that another organism provides. These relationships are based on the advantages that can be gained by finding and using a previously unexploited niche. Competition and predation are ecological relationships but are not symbiotic. Predation does not occur over a long period of time, and competition is an indirect interaction over resources.
