Answer:
Organic pathway.
Explanation:
The organic pathway of the carbon cycle moves carbon from the atmosphere, through producers such as plants and algae etc in the process of photosynthesis and back to the atmosphere in the process of respiration of living organisms. In the process of photosynthesis, carbondioxide is taken by the plant from the air to make glucose. When this glucose is eaten by the animals, it again converted into carbondioxide gas in the process of respiration and goes to the atmosphere again.
