Renewability and Carbon Cycle in Biofuel Production

Steps:

• Identify statement 1: Sugar cane is a plant that regrows annually, classifying it as renewable.
• Confirm statement 2: Photosynthesis in growing sugar cane absorbs CO2 from the air to produce glucose.
• Evaluate renewability: Non-renewable resources like fossil fuels deplete without natural replenishment; biomass like sugar cane renews via growth cycles.
• Conclude: Only statement 2 holds true based on biological processes.

Why B is correct:

• Statement 2 aligns with the photosynthesis equation (6CO2 + 6H2O → C6H12O6 + 6O2), where plants remove atmospheric CO2 during growth.

Why the others are wrong:

• A: Includes false statement 1, as sugar cane regenerates naturally.
• C: Combines true and false statements, making it incorrect.
• D: Dismisses valid statement 2 on CO2 absorption.

Final answer: B
