Question

analysis questions: 1. describe the journey that a carbon atom inside a fossil fuel will take to become a carbon atom inside a plant. 2. describe the journey that a carbon atom from inside a volcano will take to become a carbon atom inside a fossil fuel.

Explanation:

1. When a fossil - fuel is burned, carbon atoms are released into the atmosphere as carbon - dioxide. Through the process of photosynthesis, plants take in carbon - dioxide, and the carbon atoms become part of the plant's structure.
2. When a volcano erupts, carbon - containing compounds are released into the atmosphere. This carbon - dioxide can be taken up by plants during photosynthesis, or it can remain in the atmosphere. Eventually, through various ecological and geological processes, the carbon can be incorporated into new organic matter or geological formations.

Answer:

1. Fossil fuel is burned, releasing carbon as carbon - dioxide. Plants take in carbon - dioxide during photosynthesis, and the carbon becomes part of the plant.
2. Volcano erupts, releasing carbon - containing substances. Carbon - dioxide can be taken up by plants or cycle through the atmosphere and other Earth systems until it becomes part of new carbon - containing entities.
