Question
Chapter 16, Problem 1SL
Summary Introduction
To determine:
The production and use of biofuels in the United States and also the role of government, private industry, and scientists in promoting the production and use of biofuels.
Introduction:
Biofuels are the substitutes for fossil fuels and are derived from renewable animal and plant biomass. Biodiesel and ethanol are the two types of biofuels.
Summary Introduction
To determine:
Whether citizens have an ethical responsibility to use biofuels as a substitute for fossil fuels and provide a reason for the same.
Introduction:
Ethanol, biodiesel, and biogas are examples of biofuels. Ethanol is often made from corn or sugarcane. Biogas (methane) derives from animal manure and other digested organic material.

The biofuel can be combined with gasoline to increase the energy outputs in automobile engines. How will the use of biofuel change how humans use energy resources? Biofuel will decrease the use of gasoline in the automobile industry, decreasing the need for nonrenewable energy resources. Biofuel will decrease the production of algae in the automobile industry, decreasing the need for nonrenewable energy resources. Biofuel will decrease the amount of fuel for automobiles, increasing the need for renewable energy resources.

- Photosynthesis plays an important role in maintaining life in most ecosystems on Earth because it has an impact on how organisms obtain their energy. Write a claim that supports the idea that photosynthesis helps sustain life on Earth, and support that claim with at least one piece of evidence.arrow_forwardAs scientists research and develop biofuels, they are faced with many tradeoffs. A plant's usefulness for biofuels depends on how much energy can be collected from the plant matter. In addition, growing plants on a large scale requires energy—such as the gasoline and power needed to run tractors and other harvesting equipment or the energy needed to create and distribute fertilizers and pesticides. An efficient biofuel would maximize the ratio of energy output to energy input. The following graph illustrates the results of a 10-year study analyzing three different crops used in biofuel production. The data show how much energy was required to grow each crop on 1 hectare of land (energy input) and how much energy was recovered from the total crop on each hectare of land (energy output). A hectare is a measurement of an area of land and is roughly the same as 2.5 acres. What was the estimated energy input of the grass? A. 2 kcal × 106 B. 4 kcal × 106 C. 8 kcal…arrow_forwardAs scientists research and develop biofuels, they are faced with many tradeoffs.
