It is so because there is an increase in the number of superior competitors which eventually exclude the lesser competitors. Therefore there is a loss in species diversity.

<h3>What is species diversity?</h3>

It is defined as the number of different species present in an ecosystem and relative abundance of each of those species.
Diversity is greatest when all the species present are equally abundant in the area.
Due to more resources, one species becomes dominant and excludes others.
Diversity is inversely proportional to dominance.
Species diversity is usually highest at intermediate values of resources.
