Based on the information provided in the diagram and the processes referenced (photosynthesis and respiration), Charlie can answer the question: "Where is glucose stored after it is created through photosynthesis?"
The diagram outlines processes involving sunlight, water, carbon dioxide, glucose, and oxygen, which align with photosynthesis. Therefore, questions regarding the storage or function of glucose produced during photosynthesis are directly relevant to the diagram's content. The other questions mentioned do not align as clearly with the diagram of photosynthesis.
