Answer:
The correct answer will be- Keystone species
Explanation:
The structure of a community is largely determined by the number of species present in the community called species richness and the species diversity.
The species which can play an important role in determining the community could be of two types the foundation species and keystone species.
The species which directly influence the diversity of a community irrespective of their number and abundance is known as the keystone species.
In the given question since the question has discussed the species which disproportionately influence the diversity of the community is known as keystone species.
Thus, keystone species is the correct answer.
