Question

Competitive exclusion is the result of ____ by two species for the same limiting resource.  
A) mutualism
B) commensalism
C) competition
D) symbiosis
E) parasitism

Accepted Answer

Competitive exclusion occurs when two or more species compete for the same limiting resource, which results in one species outcompeting and eventually eliminating the other species from the ecosystem. Mutualism, commensalism, symbiosis, and parasitism do not necessarily result in competitive exclusion.
