3. Describe how population growth rate is calculated.

4. Describe how and explain why each of the following factors affects the growth of a population:

birth rate
death rate
immigration
emigration
population growth rate
fecundity
biotic or intrinsic factors
exponential population growth
logistic population growth
density dependent environmental resistance factors
density independent environmental resistance factors

5. Explain the distinction between density dependent and density independent environmental resistance factors that regulate population growth.

6. Explain the relationship between the concepts, environmental resistance factors, birth rate, death rate, population growth rate, and carrying capacity.
