Question

carbon returns to living organisms through which of the following processes? combustion cellular respiration fossilization photosynthesis

Explanation:

Cellular respiration breaks down organic compounds (containing carbon) to release energy for cells, returning carbon - containing compounds to living organisms. Combustion releases carbon into the atmosphere from non - living sources. Fossilization removes carbon from the short - term cycle into long - term storage. Photosynthesis takes in carbon dioxide from the atmosphere to build organic compounds but doesn't return carbon to living organisms in the way the question asks.

Answer:

B. Cellular Respiration
