What is the role of carbon dioxide in the carbon cycle?

• Carbon dioxide is released into the atmosphere through natural processes and human activities, and is used by plants and algae during photosynthesis.

• Carbon dioxide is not involved in the carbon cycle.

• Carbon dioxide is only released into the atmosphere through human activities.

• Carbon dioxide is produced by animals during respiration.

What is the role of plants in the carbon cycle?

• Plants release carbon dioxide and nitrogen during photosynthesis.

• Plants do not play a role in the carbon cycle.

• Plants absorb carbon dioxide and release oxygen during photosynthesis.

• Plants release carbon dioxide and absorb oxygen during photosynthesis.

What is the role of animals in the carbon cycle?

• Animals contribute to carbon sequestration through deforestation.

• Animals play no role in the carbon cycle.

• Animals only release carbon dioxide through respiration.

• Animals release carbon dioxide through respiration and decomposition, and contribute to carbon sequestration through biomass formation and plant consumption.

What is the role of decomposers in the carbon cycle?

• Decomposers convert carbon dioxide into organic matter.

• Decomposers release oxygen into the atmosphere.

• Decomposers break down dead organic matter and release carbon dioxide.

• Decomposers absorb carbon dioxide from the atmosphere.
