Nature generally checks the unlimited growth of populations through many ways. One of the important factors that influence the growth of populations is the “finite carrying capacity” of the environment in which the species grow. The term carrying capacity is a parameter representing the resources, e.g., food, space, sunlight, etc. on which the species grow. If the initial size of the population is small, the population grows approaching the carrying capacity of the environment and if, the population is initially very large, it decreases approaching the carrying capacity asymptotically.
