Why is photosynthesis considered a carbon sink?

• It removes carbon dioxide from the atmosphere.

• It adds carbon dioxide into the atmosphere.

• It coverts oxygen into carbon dioxide.

• Photosynthesis releases carbon dioxide into the atmosphere during the process.

Which of the following is considered an inorganic carbon reservoir?

• Plants

• Animals

• Microbes

• Rocks

What process removes carbon dioxide from the atmosphere and converts it into glucose?

• Respiration

• Decomposition

• Photosynthesis

• Combustion

Which of these processes releases carbon dioxide back into the atmosphere?

• Photosynthesis

• Respiration

• Sedimentation

• Formation of sedimentary rocks

Why is respiration called a carbon source?

• It removes carbon dioxide from the atmosphere.

• It adds carbon dioxide into the atmosphere.

• Plants converts sugar into carbon dioxide.

• Animals convert carbon dioxide into sugar.

Why is the biological carbon cycle called the fast carbon cycle?

• It describes slow geological processes of carbon storage.
• It focuses on carbon sequestration in ocean sediments.
• It highlights the role of fossil fuels in carbon release.
• It involves rapid processes of carbon exchange between living organisms and the atmosphere.

Why are coal, oil and natural gas called fossil fuels?

• They are called fossil fuels because they originate from the remains of ancient organisms.
• They are called fossil fuels because they are found in deep ocean beds.
• They are called fossil fuels due to their high carbon content.
• They are called fossil fuels because they are renewable energy sources.
