Predators that are keystone species can maintain species diversity in a community if they a. competitively exclude other predators. b. prey on the community's dominant species. c. reduce the number of disruptions in the community. d. prey only on the least abundant species in the community.

Hello everyone. And in today's video we have the following problem. If a predator praise on the community's dominant species or the species that is feeding off of every other species it would be regarded as a keystone species. So this product er will be regarded as a keystone species because remember a keystone species or species that are essential to the survival of the ecosystem. Now let's visualize what is happening in this traffic relationship. So we have a dominant species as we see here that is fit enough species or different praise within the ecosystem. When this dominant species is feeding off of of of this praise uncontrollably the diversity is gonna go down as they will most likely this praise will most likely go extinct from over hunting. However if we introduce a predator that is going to feed off or just keep these dominant species in check and not allow it to over hunt these prey species. The species diversity of the ecosystem is actually going to be maintained. Which is what we see here. The species diversity won't be decreased because the predator is stopping these dominant species from over hunting other species within the ecosystem maintaining species diversity. So that is going to be the final answer to our problem and we're going to highlight it. It's going to be the end of the video. I really hope it helped you and I hope to see you on the next one
