Question
Which diagram correctly represents the carbon dioxide-oxygen cycle?
Answers
GPT-4o mini
The carbon dioxide-oxygen cycle, also known as the photosynthesis-respiration cycle, can be illustrated with a diagram that shows the following key processes:
1. **Photosynthesis**: Plants (and some microorganisms) take in carbon dioxide (CO₂) from the atmosphere and water (H₂O) from the soil. Using sunlight, they convert these into glucose (C₆H₁₂O₆) and release oxygen (O₂) as a byproduct.
2. **Respiration**: Animals (and plants) take in oxygen (O₂) from the atmosphere to break down glucose (C₆H₁₂O₆) for energy. This process releases carbon dioxide (CO₂) and water (H₂O) back into the atmosphere.
3. **Decomposition**: When living organisms die, decomposers break them down, releasing CO₂ back into the atmosphere.
A good diagram will clearly show these processes and their relations, typically with arrows indicating the flow of materials. If you're trying to choose a specific diagram from a set you're looking at, look for one that includes these elements:
- Arrows indicating the movement from plants to animals (for O₂ and glucose) and from animals back to plants (for CO₂).
- A connection between the process of photosynthesis and respiration.
- Possibly the role of decomposers in releasing CO₂ into the atmosphere.
