Symbiosis is a close relationship between two species in which at least one species benefits. Mutualism is a symbiotic relationship in which both species benefit., Parasitism is a symbiotic relationship in which one species (the parasite) benefits while the other species (the host) is harmed.
Symbiosis is any type of a close and long-term biological interaction between two different biological organisms, be it mutualistic, commensalistic, or parasitic. The organisms, each termed a symbiont, may be of the same or of different species
Hello Dear, Symbiotic relationships can be obligate or facultative. Obligate symbiosis is when two organisms are in a symbiotic relationship because they can't survive without each other.
