Final answer:
The addition of a predator to an ecosystem usually leads to a decrease in the population of its prey by consuming a portion of the prey population. This creates balance and prevents overpopulation.
Step-by-step explanation:
Adding a predator to an ecosystem can have a significant impact on the population of its prey. In most cases, the population of the prey would decrease because the predator would consume a portion of the prey population. This leads to a decrease in competition for resources and allows the remaining prey individuals to reproduce and increase their population.
For example, let's consider a population of rabbits and add a population of foxes as their predator. Initially, there might be a large number of rabbits due to the absence of a predator. However, when the foxes are introduced, they will start preying on the rabbits. As the predator consumes the prey, the rabbit population will gradually decrease, as they are being killed. This decrease in the rabbit population will help control their numbers and prevent overpopulation.
Overall, the addition of a predator can lead to a decrease in the population of its prey, resulting in a more balanced ecosystem.
