WebThe name “Logistic function” which has nothing to do with military or industrial Logistics, was given by Verhulst, Citation 3 during a study on population growth. By definition, a Logistic curve tends to approach maximal value (m) as the given x approaches +∞ and it approaches 0 as x approaches −∞. WebB14. Which of the following statements characterize(s) the logistic growth of a population whose limiting value is L and whose initial value is less than 2 L ? I. The rate of growth increases at first. II. The growth rate attains a maximum when the population equals 2 L . III. The growth rate approaches 0 as the population approaches L.

If a population is growing in a constrained environment with carrying capacity K, and absent constraint would grow exponentially with growth rate r, then the population behavior can be described by the logistic growth model: P n =P n−1 +r(1− P n−1 K)P n−1 P n = P n − 1 + r ( 1 − P n − 1 K) P n − 1.
