Answer:
The two substances found in the carbon cycle are carbon dioxide (CO₂) and organic carbon compounds (e.g., glucose, C₆H₁₂O₆).
Explanation:
In the carbon cycle, carbon dioxide (CO₂) is a key component found in the atmosphere. It is absorbed by plants during photosynthesis and converted into organic carbon compounds, such as glucose (C₆H₁₂O₆). These organic compounds are then used by plants and animals for energy and growth. When organisms respire, decompose, or burn fossil fuels, the organic carbon is converted back into carbon dioxide, which is released back into the atmosphere, completing the cycle.
