Which gas is released into the atmosphere through the burning of fossil fuels?

• Oxygen

• Carbon dioxide

• Nitrate

• Nitrogen

What role do decomposers play in the cycling of material in a biogeochemical cycle?

• Decomposers make chemicals from the nonliving environment into organic compounds.

• Decomposers incorporate some organic compounds into their bodies and release some back to the environment as waste

• Decomposers break down organisms to supply the soil, water, and air with inorganic chemicals.

• Decomposers use non living processes such as rain and fire to make inorganic chemicals.
