Energy limitation is probably the most important determinate, but such factors as food, availability of shelter, and the amount of competition can also influence this.  A sigmoid-shaped graph results when this factor is included in a model of growth.  Such an equation is called a logistic growth equation.  FTP, name this quantity symbolized by a capital K, the maximum stable population size of a species that an environment could support over a period of time.
