Asked by Cordova
Can you explain in simple terms the following:
An organism is sealed in a chamber. Scientists measure amount of oxygen and carbon dioxide in the chamber. How do they use the volume of these gases to determine if photosynthesis or cellular respiration is occurring in the chamber?

Sure! Think of it this way:
1. **Photosynthesis vs. Cellular Respiration**:
- **Photosynthesis** is when plants use sunlight to turn carbon dioxide (CO₂) and water into oxygen (O₂) and glucose (a type of sugar).
- **Cellular Respiration** is when organisms (like plants, animals, and humans) take in oxygen and glucose to produce energy. This process creates carbon dioxide and water as waste products.
2. **How Scientists Measure Gases**:
- Scientists can seal an organism in a chamber and then measure the amount of oxygen and carbon dioxide present inside.
- They look at how the levels of these gases change over time.
3. **Determining What's Happening**:
- If the **amount of oxygen increases** and the **amount of carbon dioxide decreases**, it suggests that **photosynthesis** is occurring. This is because plants are taking in carbon dioxide and releasing oxygen.
- Conversely, if the **oxygen level decreases** and the **carbon dioxide level increases**, it means **cellular respiration** is taking place. This shows that the organism is using oxygen and releasing carbon dioxide.
By observing these changes, scientists can tell whether photosynthesis or cellular respiration is happening in the chamber.
