Here are the correct responses to complete the statements about photosynthesis and the carbon cycle:
1. Photosynthesis is the **chemical** reaction by which plants produce complex food molecules (sugars). This process requires an energy input from **sunlight** to occur. In this reaction, the **reactants** carbon dioxide and water combine to form **products** such as glucose and oxygen gas. Photosynthesis is an important part of the carbon cycle because it removes **carbon dioxide** from the atmosphere.
To summarize:
1. chemical
2. sunlight
3. reactants
4. products
5. carbon dioxide
