Q. With reference to the Carbon Cycle in nature, consider the following statements:
1.The carbon cycle includes both short-term exchanges through processes like photosynthesis and respiration.
2.Carbon stored in deep ocean sediments and fossil fuels is permanently locked and cannot re-enter the atmosphere.
Which of the statements given above is/are correct?
Answer: A
Notes:
Explanation:
- The carbon cycle includes both short-term exchanges through processes like photosynthesis and respiration, and long-term storage in sediments and fossil fuels.
- Carbon stored in sediments and fossil fuels can return to the atmosphere — through erosion, geological uplift, and combustion (burning of fossil fuels), releasing CO₂ back into the atmosphere.
