limestone and coral
acid rain
atmosphere
dead organic matter, humus
organisms (carbon dioxide gas) (carbohydrates) (calcium carbonate) (carbon) (carbonic acid)

Answer 1

Sure! Here’s how you can match the carbon sources to the appropriate spheres in the carbon cycle:

1. Atmosphere:

   • (carbon dioxide gas)

2. Hydrosphere:

   • (carbonic acid)

3. Biosphere:

   • (carbohydrates)
   • (dead organic matter, humus)
   • (organisms)

4. Geosphere:

   • (calcium carbonate)
   • (limestone and coral)
