WebGraph Interpretation. Population growth, a common topic in population ecology, plots population size over time on a graph. Before learning about population growth, let’s test … WebThus, the exponential growth model is restricted by this factor to generate the logistic growth equation: dN dT = rmax dN dT = rmaxN (K −N) K d N d T = r m a x d N d T = r m a x N ( K − N) K. Notice that when N is very small, ( K-N )/ K becomes close to K/K or 1, and the right side of the equation reduces to rmaxN, which means the ...
