Question

Quizplus · Accepted Answer

Parasites can drain nutrients from hosts, weaken their immune systems, and cause illness or death, which can lower birth rates and raise death rates. Additionally, parasites can change the behavior of hosts and make them more vulnerable to predation. Some parasites can also cause sterility or reduce the fitness of the offspring, further impacting the population dynamics of the host. Therefore, all of these factors contribute to the impact of parasites on host populations.
