8.4 Effect of Density on Populations
In short
You must understand the relationship between population density and resource availability, specifically how resources determine the carrying capacity of an environment. You need to know that carrying capacity is the maximum sustainable population size. The topic requires understanding that density-dependent and density-independent factors limit growth, leading to a logistic growth model.
