B. Social welfare issues due to floods or drought conditions.
C. Only A..
D. Urban sprawl.
E. Both and A and B
2. To say that environmental science is mission-oriented means it is

D. designed to understand relationships.
3. Which of the following is not an anticipated result of global warming?
A. Extended growing seasons for crops with a corresponding increase in yield.
B. Increased frequency of droughts and widespread severity of storms
C. Increased absorption by the oceans of CO2 with a corresponding increase in ocean water pH
D. Reduction of the size of the Arctic Sea ice by 1 million sq. km in the past 30 years.
E. Change in global disease patterns
4. You are studying a wolf pack in lower Alaska for a period of 10 years. You record their birth and death rates, along with the birth and death rates of their main prey, a deer species. If this wolf population is controlled by "carrying capacity," which of the following would you expect to see:
A. Wolves are omnivores, so they will not be affected by fluctuations in the deer population.
B. As they overshoot their carrying capacity, wolf death rates will rise.
C. As they overshoot their carrying capacity, wolf birth rates will rise.
D. Their population will crash before their prey population peaks.
E. The deer population will crash 1 year after the wolves overshoot their carrying capacity.
5. Which of the following is a real difference between exponential and logistic growth:
A. Populations without resource limitations grow exponentially.
B. Populations without resource limitations are affected by carrying capacity.
C. Logistic growth starts slowly and proceeds rapidly as the population increases.
D. Both A and C.
E. All of the above are true.
6. The total productivity of an ecosystem refers to the
A. Amount of food consumed by the organisms per unit space
B. Average number of offspring produced per adult female per unit time
C. Amount of biological material produced during a certain period of time
D. Reproductive output
7. Which of the following would not be an act of predation?
A. A moose nibbling on aspen shoots
B. A crow feeding on a road-kill rabbit
C. A black bear eating blueberries
D. Disease-causing bacteria invading human lung tissue
8. This age structure diagram shows you the age distribution of a hypothetical population: the blue boxes denote ages 0-14; green = 15-44; and maroon = 45+ years of age. Which of the following can you conclude about this population?
A. This population has slow growth like the U.S. or Italy.
B. This population has fast growth like Austria or Canada.
C. This population has great potential to harm the environment due to its fast growth.
D. This population is better for the environment than China because it has a high probability of reproduction.
E. The number of working people exceeds to number of nonworking people, which is favorable for the environment.
9. You just completed NSCI 362 and are well aware of the environmental toll a typical American meal takes on the environment-so you decide to make a locally-sourced dinner for some visiting relatives. You visit a local farmer's market to get the bulk of your ingredients with an additional trip to a local farm for grass-fed beef steaks. When you serve your guests, you rave about the ingredients and how fresh and local they are. One of your guests has a Ph.D. in environmental science-which of the following is likely to be his appraisal of your meal:
A. Wow! I didn't realize what an eco-minded person you are! Where did you learn about this stuff?
B. This is great, but it's so much more important to focus on certified organic ingredients, even if they're not locally sourced.
C. This is superb, but the local beef is far more important than the local vegetables, given the CH4 emissions from cattle.
D. This is great, but if you really want to make an environmental impact, keep the meal local and meat-free.
10. Using the below figure, which answer correctly describes what happened to the pest and/or predator populations(s) following the pesticide application?
A. The pest and predator population crashed. Both did not recover.
B. The pest and predator population crashed. The pest population then increased dramatically.
C. The predator population crashed and then increased dramatically.
D. The pest population was unaffected by the pesticide application.
E. The predator population was unaffected by the pesticide application.
