Text Solution
Verified by ExpertsThe correct answer is:
C
Totally unrelated species could also compete for the same resource. Resources need not be limiting for competition to occur; in interference competition, the feeding efficiency of one species might be reduced due to the interfering and inhibitory presence of the other species, even if resources (food and space) are abundant. Interspecific competition is a potent force in organic evolution.
