The correct answer is ecological isolation.
Explanation:
The condition when two species in spite of living in the same region, exhibits certain characteristics, which inhibits them from mating with each other is termed as reproductive isolation. The obstructions or the causes that prevent them from interbreeding is known as isolating mechanisms.
The given case is an example of ecological isolation and is one of the forms of reproductive isolation. Habitat or ecological isolation refers to the phenomenon in which two species cannot mate with each other as they thrive in two distinct locations.
