Interactions between organisms and their environment impact the organism’s overall population. oahu amakihi and kauai amakihi are two closely related species of hawaiian honeycreepers. they have a common ancestor, eat small insects and nectar, and like to nest in koa trees. however, one species is found on the island of oahu, and the other is found on the island of kauai. which concept shows the relationship between the oahu amakihi and the kauai amakihi?

The given association between the Oahu amakhi and Kauai amakhi can be illustrated by the notion of the competitive exclusion principle. In ecology, competitive exclusion principle is on certain occasions also termed as the Gause's law.  

On the basis of this principle, the two species contending for the similar restraining resource cannot live together at the obstinate population values. Even if one of the species possesses a small advantage over the other, then the one with the plus will govern for a long time. This leads to either a behavioral or the evolutionary shift towards an altered ecological niche or the culmination of the weaker contestant.
