What will happen to a population of predators if there is a sudden, temporary increase in the number of prey?
alekssr [168]
The number of predators and preys change from time to time following cycles. Whenever there is fewer prey, predators start dying because they have not enough to eat; however, that provokes the population of prey to be increased while there are fewer predators. So if suddenly the number of prey gets bigger, regardless of the number of predators, the cycles get disturbed by this sudden occurrence. The predators will get more to hunt, therefore getting more violent.
