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 oahu amakihi and kauai amakihi?

The association between Oahu amakhi and Kauai amakhi can be demonstrated by the concept of competitive exclusion principle.  

The competitive exclusion principle in ecology is sometimes also known as the Gause's law. According to this principle, the two species fighting for the similar restricting resource cannot cohabit at the persistent population values. If one of the species even exhibit the slightest advantage over another, then the one with the benefit will dominate in the prolonged time.  

This results in either an evolutionary or behavioral shift towards a distinct ecological niche or the extinction of the weaker competitor.
