Which of the following could be true of two different species that have a competitive relationship in the same ecosystem?
a.) one species preys on the other.
b.) the relationship is mutually beneficial.
c.) they share the same niche.
d.) one species benefits, while the other is neither nor harmed.

C (they share the same niche)

Explanation:

Competition is a relationship between organisms resulting in a contest when both are trying to use the same resources related to their growth, reproduction and survivability. It is as a result of limited resources. Competition occurs in virtually all ecosystems in nature. This relationship develops when more than one organism in an environment has the same need for resources (niche) as another, to survive.

Each organism has a specific place in the ecosystem called NICHE. A species' niche is basically its ecological role or the function to which it is especially suited, which is defined by the set of conditions, resources and interactions it needs or can use.

The competitive exclusion principle says that two species can't coexist if they occupy exactly the same niche (competing for identical resources) or to put it in another way, two species in an ecosystem are bound to compete when they share the same niche (need for resources).
