Idealized models predict patterns of population growth. Exponential growth is the accelerating increase that occurs when growth is unlimited. The equation G = rN describes this J-shaped growth curve; G = the population growth rate, r = an organisms inherent capacity to reproduce, and N = the population size. Logistic growth is the model that represents the slowing of population growth as a result of limiting factors and the leveling off at carrying capacity, which is the number of individuals the environment can support. The equation G = rN(K N)/K describes a logistic growth curve, where K = carrying capacity and the term (K N)/K accounts for the leveling off of the curve.
