Question

8. Which arrow or arrows represent a release of carbon dioxide? What process is occurring at the arrow(s) you selected? B, C and D are forms of carbon dioxide because as they the water or chemicals are being evaporated, it produces carbon dioxide which filters out the air.
9. Which arrow or arrows indicate a process that cycles carbon from living or nonliving organisms? Describe the process or processes you selected.

Answer 1

The arrow C represents the emission of carbondioxide in the atmosphere. As you can see that the arrow is from the smoke that is emitted from the factories and industries and to the carbondioxide in the atmosphere.

The combustion process releases carbondioxide in the atmosphere. The combustion of fossil fuels releases carbon which is the underlying process representing arrow C

The arrow B represents the intake of carbondioxide by plants during photosynthesis to release oxygen

The arrow C represents the release of carbondioxide from industries due to the combustion of fossil fuels

The arrow D represents the dissolving of the carbondioxide into carbonates in the water bodies

Question 9:

The death and decay of the plants and animals that go underground converts the organic carbon in them into the inorganic form that forms fossils and fossil fuels. This process if indicated by the arrow E
