What is one of the most important processes that removes carbon from the atmosphere? 

• photosynthesis
• cellular respiration
• erosin
• soil respiration

Which process moves carbon stored in fossil fuel into the atmosphere?

• When fossil fuels are burned, carbon enters the atmosphere as carbon dioxide.
• The denitrifying bacteria turns the fossil fuel into carbon dioxide gas.
• Decomposers convert the fossil fuels into greenhouse gases like carbon dioxide.
• The fossil fuels react with the soil to produce carbonates and carbon dioxide.

What is happening in step
1?

• Animals are decomposing and realizing carbon into the soil.
• Animals are releasing energy into the environment and storing carbon.
• Animals are turning carbon dioxide from the atmosphere into organic molecules.
• Animals are breaking down organic molecules and releasing carbon dioxide into the atmosphere.
