Symbiotic Relationships
Symbiosis- the interaction between two different organisms living in close physical association, typically to the advantage of both.
Mutualism- when two organisms of different species "work together," each benefiting from the relationship.
Commensalism- an association between two organisms in which one benefits and the other derives neither benefit nor harm.
Parasitism- a non-mutual symbiotic relationship between species, where one species, the parasite, benefits at the expense of the other, the host.
