Explanation:

Mutualism is a symbiotic relationship where both organisms benefit. Bacteria in human microbiomes help humans survive and humans provide bacteria with a living place, which fits the definition of mutualism. Predatory relationships involve one organism killing and eating another. Parasitic relationships have one organism (parasite) benefiting at the expense of the other (host). Competitive relationships are about organisms competing for resources.

a mutualistic relationship
