Question

Quizplus · Accepted Answer

Gause's laboratory experiments with Paramecium species provided evidence for the competitive exclusion principle, which states that two species with identical niches cannot coexist indefinitely; one will eventually outcompete and exclude the other. Through his experiments, Gause showed that when two Paramecium species with similar niches were grown together in a limited resource environment, one species would eventually outcompete and exclude the other.
