How are carrying capacity and population density related?

Population density is the object of any logistic growth analysis. It is its "raison d'être" since, in most cases, it is the problem to anticipate or to resolve. If, in a given area at any given time, there is a given num Population density is one of the factors of an equilibrium. Carrying capacity is the upper limit of each factor within the equilibrium. ber of preys, only a given number of predators can survive within that area.
