Which statements accurately describe the roles of decomposers in the carbon cycle? Select three options.Decomposers release carbon dioxide into the air as waste.Decomposers remove carbon dioxide from the air during photosynthesis.Decomposers break down the remains of dead plants and animals.Decomposers return carbon compounds to the soil.Decomposers use carbon to make food molecules.
Sample Response: Human activity can affect the amount of carbon in the atmosphere. When fossil fuels like oil, coal, and natural gas are burned, carbon dioxide is released into the atmosphere as waste. The clearcutting of forests for lumber and fuel also increases levels of carbon dioxide in the atmosphere because the trees can no longer remove carbon dioxide from the atmosphere for photosynthesis. If trees are burned in order to be cleared, the burning processes release even more carbon dioxide
What is free nitrogen?
How do plants obtain nitrogen?
Once water vapor has been released into the atmosphere, it rises and cools, turning back into a liquid. What is this process called?

Sample Response: When farmers harvest crops, a lot of the plant material is also removed. Little is left to decay and return nitrogen to the soil. If the soil stays this way, it will start producing fewer crops. Fertilizer contains the nitrogen compounds that are essential for plant growth. It can be used to replace the nitrogen in the soil to ensure the growth of healthy crops. What did you include in your response? Check all that apply.When farmers harvest crops, a lot of the plant material is
