Direct link to Michael Ma's post what does the max mean af, Posted 5 years ago. View Answer. In this model r does not change (fixed percentage) and change in population growth rate, G, is due to change in population size, N. As new individuals are added to the population, each of the new additions contribute to population growth at the same rate (r) as the individuals already in the population. In fact, maximum population growth rate (G) occurs when N is half of K.
