What is most likely to happen if predators are introduced to an ecosystem with no known predators?

Answer 1

If predators are introduced to an ecosystem with no known predators, it is likely that the prey populations in that ecosystem will experience a decrease in numbers. The predators will likely hunt and prey on the animals that were previously free from predators, leading to a disruption in the balance of the ecosystem. This can cause a cascading effect on the other species in the ecosystem, leading to changes in the population dynamics and potentially even causing some species to become endangered or extinct. Additionally, the introduction of predators can also lead to changes in the behavior and distribution of the prey species as they adapt to the new threat.
