Q. Which of the following ways carbon is added to atmosphere in carbon biogeochemical cycle?
Select the correct answer using the code given below:
Carbon is present in the atmosphere, mainly in the form of carbon dioxide (CO2). Carbon cycle involves a continuous exchange of carbon between the atmosphere and organisms.
- Carbon from the atmosphere moves to green plants by the process of photosynthesis, and then to animals.
- By process of respiration and decomposition of dead organic matter it returns back to atmosphere. It is usually a short-term cycle.
