As resources diminish, each individual on average, produces fewer offspring than when resources are plentiful, causing the birth rate of the population to decrease. In exponential growth, the population growth rate (G) depends on population size (N) and the per capita rate of increase (r). Carry out the experiment shown in the Duckweed population growth experiment worksheet. The Quarterly Review of Biology. Add highlights, virtual manipulatives, and more. Initially when the population is very small compared to the capacity of the environment (K), \( 1- \frac {N} {K}\) is a large fraction that nearly equals 1 so population growth rate is close to the exponential growth \( (r \times N) \). The data is plotted on a graph where the student will clearly see the initial exponential growth of the population followed by logistic growth.
