Carbon Cycle Review

Which tectonic processes recycle carbon back to land and the atmosphere?

• Erosion and deposition

• Subduction and uplifting

• Folding and faulting

• Weathering and erosion

What is the main product of photosynthesis that serves as a sugar?

• Fructose

• Sucrose

• Glucose

• Lactose

What is the main gas absorbed by plants during photosynthesis?

• Oxygen

• Nitrogen

• Carbon dioxide

• Methane

Which of the following is a key component of the photosynthesis equation?

• Nitrogen

• Sulfur

• Water

• Phosphorus

What process do organisms use to break down glucose?

• Photosynthesis

• Fermentation

• Aerobic respiration

• Anaerobic respiration

What are the byproducts of aerobic respiration?

• Oxygen, glucose, and ATP

• Carbon dioxide, water, and energy

• Nitrogen, water, and ATP

• Glucose, oxygen, and energy

Which of the following is NOT a product of aerobic respiration?

• Carbon dioxide

• Water

• Glucose

• Energy

What is released back into the atmosphere during aerobic respiration?

• Oxygen and glucose

• Carbon dioxide and water

• Nitrogen and hydrogen

• Helium and methane

What is the relationship between photosynthesis and aerobic respiration in the carbon cycle?

• They are unrelated

• Photosynthesis releases carbon dioxide, aerobic respiration absorbs it

• Photosynthesis absorbs carbon dioxide, aerobic respiration releases it

• Both processes release oxygen
