Explanation:
Detailed explanation-1: -Introducing new predators can cause a rapid decline in the numbers of prey, which then reduces the food supply for existing predators.
Detailed explanation-2: -Predators have profound effects throughout their ecosystems. Dispersing rich nutrients and seeds from foraging, they influence the structure of ecosystems. And, by controlling the distribution, abundance, and diversity of their prey, they regulate lower species in the food chain, an effect known as trophic cascades.
Detailed explanation-3: -Carrying capacity refers to the number of predators and prey that can live in an area. Too many predators and not enough prey leads to predators starving and dying because they can’t find enough food.
