A population’s carrying capacity(A) may change as environmental conditions change.(B) can be accurately calculated using the logistic growth model.(C) increases as the per capita population growth rate decreases.(D) can never be exceeded.
1.) At approximately what year did the human population enter an exponential growth phase?
2.) Prior to that time, what was the approximate carrying capacity of Earth?
3.) State three significant technological developments that have acted to increase the carrying capacity of Earth’s environment since that time.
4.) Provide two examples of density-dependent factors that are contributing to or have the potential to contribute to environmental resistance in human populations.
During what phase of the growth curves in each diagram is the population just beginning
to colonize an area? (C)
a) Which type of population growth appears to continue unchecked?
b) The growth curves in the Model are often referred to using the letters of the alphabet
they resemble. The logistic growth curve is sometimes referred to as an S-curve.
What letter would you use to describe the exponential growth curve?
c) What causes the population to slow down during logistic growth?
d) The maximum population an environment can sustain is affected by environmental
factors that cause the population to level out or become stable. What term is used to
describe this level of logistic growth?

- You monitor the white-tailed deer population for the Wright State campus and woods and estimate 14 deer in the first year and 21 deer in the second year. (A) Assume the deer population is growing geometrically. Based on these data, what is geometric growth rate constant (A)? (B) Geometric growth patterns can also be modeled exponentially. If modeled exponentially, would you expect the exponential growth rate constant () to be greater than, less than, or equal to 0? Why? You monitor the deer population for many years. The population grows for a few more years, then seems to stabilize around 75 deer. (C) Given this information, what would be a more appropriate model for the deer population growth? Why?
