Objectives:
After studying this material you should be able to:

1. Give an example of a population.

2. Draw a simple graph illustrating a population that is growing at an exponential rate of increase (J-shaped curve).

3. Explain how each of the following factors affects the growth of a population:
   1. birth rate
   2. death rate
   3. intrinsic rate of increase
   4. generation time (age of first reproduction)
   5. age structure
   6. logistic population growth

4. Explain the distinction between density dependent and density independent factors that regulate population growth.

5. Explain what is meant by the terms environmental resistance and carrying capacity.
