3. Any factor, besides carrying capacity, that would cause a decrease of a population

3. 4. Density dependent limiting factors- depend on the population size
5. Density independent limiting factors- affects same percentage regardless of population size
6. Density dependent show an S shaped curve

a. Food limitation
b. Predation
c. Disease
d. Parasites
e. Space
f. Water
g. Climate
h. Natural disaster
i. Human disturbances

7. 9. How does this affect humans
a. Humans are growing exponentially right now
b. What limiting factors could cause the most problems for humans
