The correct Answer is:

**Step-by-Step Solution:** 1. **Understanding Respiration in Plants and Animals**: Respiration is a process that occurs in both plants and animals where oxygen is used to break down substances to release energy. 2. **Role of Oxygen in Respiration**: During respiration, oxygen is taken in and is essential for breaking down certain compounds that are produced during photosynthesis. 3. **Identifying the Substance Produced in Photosynthesis**: The primary product of photosynthesis is glucose. Plants convert sunlight, carbon dioxide, and water into glucose and oxygen. 4. **Breaking Down Glucose**: In respiration, glucose is broken down using oxygen to release energy. This process produces carbon dioxide and water as byproducts. 5. **Conclusion**: Therefore, the oxygen taken in during respiration is used to break down glucose, which is produced as a result of photosynthesis. **Final Answer**: Oxygen taken in during respiration is used to break down **glucose** produced as a result of photosynthesis. ---
