The graph shows that the removal of the keystone species (represented by the black bars) causes a significant decrease in the diversity and abundance of other species in the community. This supports the idea that keystone species have a crucial role in maintaining the structure and stability of ecosystems, and their removal can have drastic effects. Choices A and B are incorrect because they do not accurately reflect the information presented in the graph. Choice D is also incorrect because a keystone species has a specific definition and cannot be any species.
