as prey increase, predator population goes up
|
Detailed explanation-1: -As the prey population increases, there is more food for predators. So, after a slight lag, the predator population increases as well. As the number of predators increases, more prey are captured. As a result, the prey population starts to decrease.
Detailed explanation-2: -This is because as the predators continue to eat the prey, the prey population will fall and become insufficient to support the predator population which itself then falls. However, as the predator population falls, more of the prey survive and consequently the prey population will then increase.
Detailed explanation-3: -Population dynamics Predator-prey numbers interact due to: availability of food, which increases predator numbers when high but reduces them when low; concealment, which means that some prey survive by hiding from predators; predator movement to new areas when prey numbers are low.
