True or false the competitive exclusion principle can lead to adaptation of organisms trying to occupy the same niche.

The answer is TRUE.

Species occupying the same niche will always compete for the same resources. This is why Gause coined the law of competitive exclusion. The species that has the advantage over the other will outcompete the other for resources. The weak species will, therefore, be gradually eliminated from the niche because they will not be able to reach reproductive age.

However, since competition will be disadvantegous for both species, one way that the competing species can coexist stably is by partitioning the environment and occupying different niches.
