- 1. Multiple ChoiceWhich human activity would preserve nonrenewable resources?deforestationremoving carnivores from a forestrecyclingheating homes with fossil fuels
- 2. Multiple ChoiceContinued depletion of the ozone layer will most likely result inan increase in skin cancer among humansa decrease in atmospheric pollutantsan increase in marine ecosystem stabilitya decrease in climatic changes
- 3. Multiple ChoiceThe acidity of a local stream would most likely be affected bya change in the percentage of decomposers living in the streama new source of air pollutiona new predator species being introduced to the ecosystema decrease in the amount of sunlight that reaches the stream
- 4. Multiple ChoiceIncreased industrialization will most likelydecrease available habitatsincrease environmental carrying capacityincrease the stability of ecosystemsdecrease global warming
- 5. Multiple ChoiceWhich human activity is correctly paired with its likely future consequence?overfishing in the Atlantic — increase in supply of flounder and salmon as food for peopledevelopment of electric cars or hybrid vehicles — increased rate of global warminguse of fossil fuels — depletion of underground coal, oil, and natural gas suppliesgenetically engineering animals — less food available to feed the world’s population
- 6. Multiple ChoiceWhich human activity would most likely deplete nonrenewable resources?use of natural enemies to eliminate insect pestsdevelopment of wildlife refugesgovernmental restriction of industrial pollutionincreased use of fossil fuels
- 7. Multiple ChoiceDeforestation of areas considered to be rich sources of genetic material could limit future agricultural and medical advances due tothe maintenance of dynamic equilibriumthe loss of biodiversityan increase in the ecosystem’s carrying capacitythe depletion of the ozone layer
- 8. Multiple ChoiceDeforestation by burning has been described as a "double whammy" to the environment, meaning it has 2 negative impacts. Why is this description accurate?Forest burning releases CO2 while decreasing oxygen, which disrupts cyclesDeforestation reduces the amount of oxygen in the atmosphere, which depletes the ozone layerForest clearing is often followed by land development, which often leads to increased noise pollutionDeforestation increases the number of plant and animal species by destroying habitat
