Populations : Biotic Potential
Why do most populations remain stable over time? Usually it is a result of either environmental resistance or carrying capacity. Examine some of the factors that help stabilize animal populations, and explore some of the changes that...

Logistic Growth
A video on logistic growth begins with a review of exponential growth before moving on to limiting factors. This naturally leads to a decrease in the growth rate and a discovery of carrying capacity.
