How do populations of predators and prey differ in predatism

Question

How do populations of the predators and prey differ in predatism?

Answer 1

Whenever a predator population rises at the first moment prey population tends to reduce. At a second moment diminish of the prey population and bigger population density of predators cause the predator population to reduce. The prey population then revert tendency to diminish and begins to grow.

If variations in size of populations take place in an unanticipated intensity (dissimilar from the usual intensity of the ecological interaction) for instance, due to ecological accidents killing many preys, the prey-predator equilibrium is disturbed and both species can be harmed. The existence of predator sometimes is fundamental for survival of the prey population, because the absence of predatism favors proliferation of the prey and, in some cases, when the excessive proliferation generates a population size over the sustenance capacity of the ecosystem, environmental degradation occurs and entire prey population is destroyed.
