In order to determine which element combines with carbon dioxide to form glucose, we need to understand the process of photosynthesis. Photosynthesis is the biological process in which plants, algae, and some bacteria convert carbon dioxide and water into glucose (a sugar) and oxygen using sunlight as the energy source.
During photosynthesis, carbon dioxide (CO2) is combined with water (H2O) to produce glucose (C6H12O6) and oxygen (O2). So, the correct answer is oxygen (O). Oxygen combines with carbon dioxide to form glucose during the process of photosynthesis.
Therefore, the correct answer is "Oxygen".
