______________________________
symbiosis; Symbiosis is any type of a close and long- term biological interaction between two different biological organisms.ex; this is the relationship between some species of wrasses and other fish. The wrasses "clean" the other fish, eating parasites and other things that irritate the other fish.
______________________________
parasitism; Parasitism is a type of symbiotic relationship, or long-term relationship between two species, where one member, the parasite, gains benefits that come at the expense of the host member.
example; tape worm.
______________________________
predation; Predation is the act of preying on someone or something, especially when you're talking about animals.
example; grasshopper and leaf.
