Competitive exclusion is a principle that states that no two species can completely occupy the same niche in the same habitat at the same time. It means that if two species have the same requirements for resources, then one will be a better competitor and outcompete the other, ultimately leading to the exclusion of the weaker competitor. This principle helps to explain the coexistence of different species in an ecosystem by suggesting that they have evolved to use slightly different resources or live in slightly different ways to avoid direct competition with each other.
