Question

1. a fish eats algae that grows using photosynthesis. later, the fish dies and sinks to the ocean floor. some of its carbon eventually becomes fossil fuels. which two processes will release that carbon back to the atmosphere many years later? a. decomposition and cellular respiration b. photosynthesis and decomposition c. combustion and cellular respiration d. photosynthesis and combustion

Explanation:

Fossil fuels are burned (combustion) to release carbon - containing compounds into the atmosphere. Decomposition is not relevant here as the carbon is in fossil fuel form. Cellular respiration is not applicable as it occurs in living organisms and not in the context of fossil fuel release. Photosynthesis takes in carbon dioxide, not releases it in this context. Combustion of fossil fuels releases carbon back to the atmosphere.

Answer:

C. Combustion and cellular respiration
