This shows that the number of individuals added during each reproduction generation is accelerating increasing at a faster rate. After a day and 12 of these cycles, the population would have increased from 100 cells to more than 24,000 cells. Ingrid Waldron and Jennifer Doherty. To calculate net population growth rate (r) per month, death rate is http://cf.linnbenton.edu/mathsci/bio/donaghm/upload/CalculatePopGrowthExample.pdfread more. Exponential growth may occur in environments where there are few individuals and plentiful resources, but soon or later, the population gets large enough that individuals run out of vital resources such as food or living space, slowing the growth rate. This model, therefore, predicts that a populations growth rate will be small when the population size is either small or large, and highest when the population is at an intermediate level relative to K. At small populations, growth rate is limited by the small amount of individuals (N) available to reproduce and contribute to population growth rate whereas at large populations, growth rate is limited by the limited amount of resources available to each of the large number of individuals to enable them reproduce successfully. Exponential growth is not a very sustainable state of affairs, since it depends on infinite amounts of resources (which tend not to exist in the real world).
