Which of the following would absorb carbon?

• The ocean, which leads to ocean acidification

• Animals, through cellular respiration

• Combustion, from using fossil fuel

• Volcanic eruptions, pulling carbon into the lava

How do decomposers affect the carbon cycle?

• Decomposers use carbon dioxide as part of breaking down decaying matter

• Decomposers release carbon in organic matter and release it through their own respiration

• Decomposers aid in photosynthesis with their chloroplasts

• Decomposers have no impact on the carbon cycle
