A predatory fish being introduced into a lake, resulting in a dramatic decrease in the populations of smaller fish, would most likely result in the extinction of one or more species. This is because the introduction of a predator can disrupt the balance of the ecosystem and cause a ripple effect up the food chain, potentially leading to the extinction of species that relied on the smaller fish for food or other resources.
