Which practice involves capturing and storing atmospheric carbon dioxide in soil and biomass through methods like no-till farming and reforestation?

• A. Carbon Footprint
• B. Carbon Sequestration
• C. Respiration
• D. Combustion

Answer: (B)

Carbon sequestration is about capturing and storing atmospheric carbon dioxide in soil and biomass for long periods. No-till farming helps by disturbing the soil less, which preserves soil organic matter and reduces the release of stored carbon, so more carbon stays locked in the soil. Reforestation adds living biomass—trees and other vegetation—that absorb CO2 during growth and store it in wood, roots, and soil. Together, these practices remove CO2 from the atmosphere and keep it stored, rather than releasing it. Other concepts describe emissions or release of CO2. A carbon footprint measures how much greenhouse gas is produced by a product, service, or activity, not how to store it. Respiration is how organisms release CO2 during metabolism, and combustion is burning fuels that releases CO2 and energy.
