Allowing immigration of other predators

Competitively excluding other predators

Detailed explanation-1: -Answer and Explanation: The correct option is b. In communities, a predator can increase the species diversity by consuming the dominant species (prey) in that community.
Detailed explanation-2: -Keystone predators may increase the biodiversity of communities by preventing a single species from becoming dominant. They can have a profound influence on the balance of organisms in a particular ecosystem.
Detailed explanation-3: -What Effect Do Keystones Have on an Ecosystem? Keystone species maintain the local biodiversity of an ecosystem, influencing the abundance and type of other species in a habitat. They are nearly always a critical component of the local food web.
Detailed explanation-4: -The classic, generalized example is that of predators acting as the keystone species. A single predator can keep many populations of herbivores in check, allowing all of them to coexist. It also helps to prevent the herbivores from destroying all plant life in the ecosystem unchecked.
Detailed explanation-5: -Keystone predators can maintain species diversity in a community if they competitively exclude other predators allow immigration of other predators reduce the number of disruptions in the community dominant species prey on the community’ abundant species in the community prey only on the least =
