The graph shows the worldwide human population from 1950 to 2050. Data for the future years are predictions.
According to the ideas of Thomas Malthus, what are the predicted changes to the human population after 2050?
A.
The population would continue to increase at the same rate, due to constant food supplies.
B.
The population would increase more rapidly, due to advances in technology.
C.
Eventually the population would stop increasing or would decrease, due to lack of food and living space.
D.
Eventually the population would decrease to zero, because of war, famine, or disease.
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.

- Human beings, like other K-selected species live close to carrying capacity and usually have logistic growth rates. However, population growth for humans has exhibited exponential growth for over the last 350 years (since the Industrial Revolution). Which of the following can explain this phenomenon? Select one: a. Humans have been able to achieve their biotic potential. b. Humans have increased environmental resistance by limiting density-dependent factors c. Humans have been able to continually increase their carrying capacity. d. Humans have decreased environmental resistance by increasing density-independent limiting factors.arrow_forwardWhen an environment has reached its carying capacity for a certain population, which of the following is true?
