A population is a class of similar and interbreeding organisms that inhabit a particular region. The life cycle of a population comprises three different stages namely growth, stability and decline. If the population lives in a favorable environment with ample nutritional sources and scarce competition, the population will tend to rapidly increase without constraints. It only stabilizes when the resources begin to dwindle or the population encounters other environmental factors that limit its growth. The population gradually declines and eventually dies out.
