Population Growth Curves

J Curve (Exponential Growth) Example Human Population Explanation Growth without limits Occurs with: unlimited resources, few predators, etc. See blue graph!

S Curve Example Explanation See red graph! Most populations (i.e. fish, wolves) Explanation Growth with limits Occurs with: limited resources, some predators, etc. See red graph!

A nice comparison of the two…

Boom-Bust Curve Example Explanation Bacteria Lynx/Hare example Exponential curve that exceeded it’s carrying capacity and crashed.
