Logistic growth is density-dependent

Witryna25 wrz 2014 · Density dependence occurs because the level of density in an organizational population determines the level of competition between organizations. In turn, competition reduces the rate of organizational founding (the creation of a new organization) and increases the mortality rate of organizations. WitrynaIn a logistic growth curve, exponential growth is the phase in which the population A. reaches carrying capacity B. grows quickly C. growth begins to slow down D. …
