When humans burn fossil fuels, most of the carbon quickly enters the                       as carbon dioxide.

• Water
• Atmosphere
• Sun
• Air

How do living organisms return carbon to the atmosphere in the carbon cycle?

• respiration and photosynthesis
•  decomposition and respiration

What is happening at 1?

• respiration: releasing CO2
• decomposing CO2 in the soil
• photosynthesis: absorbing CO2
• turning CO2 from the atmosphere into organic molecules

Organisms that do not decompose can be buried and become what?

• water
• nutrients
• air
