Mutualism.
Parasitism.
Symbiosis.
Commensalism.
Explanation:
Commensalism is a form of symbiosis that benefits one species of the
interaction while having no effect on the other. Mutualism benefits both
species. Parasitism benefits one species at the expense of the other.

form?
A.
B.
C.
D.
Nitrogen cycle.
Water cycle.
Carbon cycle.
Phosphorous cycle.
Explanation:
In order for living organisms to make use of nitrogen, it has to be
converted into usable form. Living organisms rely on bacteria to
accomplish this transformation.
