Population growth questions answer key 1 distinguish between exponential and logistic population growth give the equations use the exponential model of. The logistic equation is a model of population growth where the size of the population exerts negative feedback on its growth rate as population size increases, the rate of increase declines, leading eventually to an equilibrium population size known as the carrying capacity. • exponential (geometric) models work well under certain limited conditions (eg population released from environmental constraints, k) • logistic model works well for many idealized (eg laboratory) populations, and less well in nature • complicating factors include varying k, r, immigration, emigration, biotic interactions (eg.
