A. Photosynthesis and cellular respiration
B. Cellular respiration and decay
C. Decay and fossil fuel formation
Explanation:
Photosynthesis, cellular respiration, decay and fossil fuel formation are all processes that are part of the carbon cycle.
In the carbon cycle, carbon in different forms moves in the environment.
- During photosynthesis, green plants use carbon dioxide gas to manufacture their own food.
- Cellular respiration release carbon dioxide as waste product into the atmosphere.
- When plants and animals dies and decay, carbon dioxide is release from their tissues by the activities of decomposers.
- Fossil fuel formation removes carbon by accumulation of the organic matter of plants and animals.
