A person’s ecological footprint is the total amount of land required to offset a person’s carbon emissions. The table below shows ecological footprint data for five different students. Each value is a measure of the number of hectares per land required.

Which of the following is a limitation of using only the data in the table to complete an ecological footprint analysis of the different students?

• The footprint for each individual is based on simple calculations to determine approximate resource use.

• The footprint uses a top-down approach to provide a complete picture of resource use for comparison between individuals.

• The footprint uses global hectares, rather than hectares, to determine the approximate proportion of Earth’s surface needed to support the activities of an individual.

• The footprint is a static analysis and does not include all environmental impacts of an individual.

Which of the following is a characteristic of nonrenewable energy sources that distinguishes them from renewable energy sources?

• The construction of power plants that use nonrenewable energy sources is typically more expensive than the construction of those that use renewable energy sources.

• Nonrenewable energy sources are typically less harmful to wildlife and ecosystems than renewable energy sources are.

• Nonrenewable energy sources typically require additional new technology in order to be used than renewable energy sources do.

• Nonrenewable energy sources typically take a longer time to replenish than renewable energy sources do.

Students want to determine the impact of soil erosion from the development of new housing. They plan to measure the density of a species of algae growing along the bottom of a river that flows through their town. The town is built in a heavily forested area, but a large area of trees along the river was recently clear-cut to allow for the construction of a new housing development, which has caused exposed soil to wash into the river. The river flows north to south through the town and is still forested both up- and downstream of the town.

Which of the following would be the best control sample for the study?

• A sample of water collected just downstream of the southern forest

• A sample of water collected just downstream of the housing development

• A sample of water collected just downstream of the northern forest

• A sample of distilled water

Which of the following is the dependent variable in the study?

• The tract of land that was clear-cut for the housing development

• A tract of land in a heavily forested area outside of town

• The density of a species of algae growing along the bottom of the river

• The flow rate of the river from north to south

The river flows north to south through the town and is still forested both up- and downstream of the town.

Which of the following explains the variable that would be the best for students to measure to determine the direct impact of soil erosion caused by the construction project on the river?

• Water temperature, because a decrease in shading in the area would indicate an increase in soil erosion.

• Nutrient levels, because a decrease in nitrogen and phosphorus would indicate an increase in soil erosion.

• The pH level, because an increase in pH would indicate an increase in soil erosion.

• Turbidity, because a decrease in water clarity would indicate an increase in soil erosion.
