Followings are the niche characteristics of the constituent species and resource partitioning pattern in different ecosystems. Which of these would lead to competitive exclusion of species?
The competitive exclusion principle states that two species with similar niche requirements cannot coexist indefinitely in the same habitat if resources are limited. One species will typically outcompete the other and drive it to extinction or force it to adapt to a different niche to avoid direct competition. Hence, the correct answer is option 2.
