Detailed explanation-1: -There are four principles at work in evolution-variation, inheritance, selection and time. These are considered the components of the evolutionary mechanism of natural selection.
Detailed explanation-2: -The struggle for existence. Organisms produce more offspring than-given the limited amounts of resources-can ever survive, and organisms therefore compete for survival. Only the successful competitors will reproduce themselves.
Detailed explanation-3: -Selective predation can lead to natural selection in prey populations and may alleviate competition among surviving individuals. The processes of selection and competition can have substantial effects on prey population dynamics, but are rarely studied simultaneously.
