उत्तर
Each species has a specific position or functional role within the community, called a niche. According to the Gausses principle, no two species can live in the same niche. In this case, two herbivorous species are living in the same niche and feeding on phytoplanktons. It may be because of the availability of sufficient phytoplanktons/and or less number of individuals of the fish species. of the two species might have occurred. And though neither of the species has been eliminated, niche overlapping may effect the growth and development of individuals of the species.
