A more realistic model includes other factors that affect the growth of the population. In this section, we study the logistic differential equation and see how it applies to the study of population dynamics in the context of biology. WebLogistic growth models include an equilibrium population size in this model. In other words, populations grow until they reach a stable size. The population is at equilibrium when total deaths equal total births and when per capita rates of birth and death are equal. This equilibrium populations size is so important in population biology, it is ... birmingham fasteners hanceville al
