Energy Resource and Conservation

A farm is situated upstream from a fish and turtle habitat. The water in the stream flows from the farm to the habitat. A recent storm brought heavy rain to the farm. Which of the following describes why the farm must manage resources to reduce water pollution?

• There will be no effect because the habitat is far enough downstream.

• Sediment, fertilizer runoff, and other pollutants could wash downstream and harm the organisms.

• Plants from the farm will wash down the stream, replacing the plants that the fish and turtles eat.

• There will be no effect because sediment and fertilizer are good for the habitat.

Which of the following statements best describes why managing resources is important in reducing energy poverty?

• Managing resources increases the amount of energy resources produced by Earth's processes.

• Managing resources allows people to access electricity using small-scale electrical grids.

• Managing resources allows people to connect to a traditional, large-scale electrical grid.

• Managing resources decreases the distance between a community and a traditional, large-scale electrical grid.

The average American family uses more than 300 gallons of water per day at home. Explain why a city would offer a rebate to residents who switch to a low-flow toilet.

Wade is writing a report on alternative fuels such as biodiesel. Biodiesel can be used as fuel in cars and trucks to conserve nonrenewable energy resources such as fossil fuels. He learns that many crop plants, such as soybeans, corn, and cotton, can be used to make biodiesel. Wade explains that this makes biodiesel the ideal fuel because you can make more just by growing more plants. Which of the following options explains one challenge to Wade's position? Growing more plants for biodiesel fuel _______________________

• means that the crops for biodiesel need to be transported longer distances.

• takes land, soil, and water resources that could be used for growing food.

• will make us less dependent on oil resources.

• will only supply enough biodiesel for the months after harvest time.

A farmer has been growing multiple crops on their land for years using the crop rotation technique, which helps conserve the soil. The soil is very healthy. The farmer wants to simplify their workload, so they have decided to grow only corn from now on. How will this impact the soil?

• The soil will gain extra nutrients that the other plants would have taken.

• The soil will become more resistant to erosion.

• The soil will become deficient in nutrients that the other crops provided.

• The soil will be able to produce more natural fertilizers.
