1. Write an equation for Verhaulst-Pearl Logistic Growth, where.

N - Population density at a timet E.

r - Intrinsic rate of natural increase.

K - Carrying Capacity.

2. Draw a graph for a population whose population density has reached the carrying capacity.
3. Why is this logistic growth model considered a more realistic one for most animal populations?
4. Draw a growth curve where resources are not limiting to growth of a population.
