Witryna6 kwi 2016 · The formula used to calculate logistic growth adds the carrying capacity as a moderating force in the growth rate. The expression “ K – N ” is equal to the number of individuals that may be added to a population at a given time, and “ K – N ” divided by “ K ” is the fraction of the carrying capacity available for further growth. WitrynadP/dt = rP, where P is the population as a function of time t, and r is the proportionality constant.
