Carrying capacity is the maximum number of the individuals of a population that can be supported indefinitely by a habitat. Once the population reaches the carrying capacity, one or other required resources become limited which in turn does not allow the exponential growth of the population.
This type of population growth wherein the exponential increase is followed by leveling out the population as the carrying capacity is reached, is called logistic population growth.
