Answer:
Symbiosis is any type of long-term interaction between two different organisms that live in close physical association.
Step-by-step explanation:
There are three different types of symbiotic relationships: mutualism, commensalism, and parasitism.
Mutualism: both partners benefit.
Commensalism: only one species benefits while the other is neither helped nor harmed.
Parasitism: One organism (the parasite) gains, while the other (the host) suffers.
