1. Draw a graph showing exponential growth in the space below. Be sure to label the horizontal and
vertical axes. Then describe exponential growth in words. What examples of exponential growth does
your book use?
2. Draw a graph showing logistic growth in the space below. Include carrying capacity in your graph. Then
describe logistic growth in words. What examples of logistic growth does your book use?
3. Under what conditions do populations grow exponentially? Under what conditions do populations grow
logistically?
4. Population growth can be limited by density-dependent factors or density independent factors. What is
the difference between these? Provide one example of each type of factor, and explain why it is densitydependent or density-independent.
