Which statement best describes the relationship between humans and plants in the carbon dioxide–oxygen cycle?
Humans depend on oxygen released into the air by plants, and plants depend on carbon dioxide that humans release into the air.
Plants produce carbon dioxide as a product of photosynthesis and release it into the air to provide energy for humans.
Plants depend primarily on energy supplied by oxygen for photosynthesis, a process which releases carbon dioxide needed by humans.
Humans and plants use gases in the air and the energy of sunlight to produce their own food.

Below is a chart of how we get our power in the United States. What conclusion can we reach from this information?
The majority of our power comes from nonrenewable resources.
We rely heavily on solar and wind energy.
We are decreasing our use of renewable resources.
Most of our power comes from hydroelectric plants.
Wind energy is advantageous because it produces little or no pollution. A disadvantage to wind energy is:
It is nonrenewable.
Electricity is only produced when the wind is blowing.
It causes major disruption to the local ecosystem.
It is very expensive to continually produce electricity.
