1 Population Growth Curves

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

3 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!

4 A nice comparison of the two…

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