Detailed explanation-1: -Decrease in preys population would lead to a decrease in predator’s population because many predators will die of hunger.

Detailed explanation-2: -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-3: -Predator and prey populations cycle through time, as predators decrease numbers of prey. Lack of food resources in turn decrease predator abundance, and the lack of predation pressure allows prey populations to rebound.

Detailed explanation-4: -As the prey population decreases, the predator population begins to decrease as well. The prey population is a limiting factor. A limiting factor limits the growth or development of an organism, population, or process.

Detailed explanation-5: -However, as the predator population falls, more of the prey survive and consequently the prey population will then increase. This in turn leads to an increase in the predator population since it has more food and the cycle begins again.
