energy + 6co₂ + 6h₂o → 6o₂ + c₆h₁₂o₆

Explanation:

To solve this, we analyze each phrase:

• Can Be Explained Using This Model of Photosynthesis: The photosynthesis equation (energy + \(6\text{CO}_2 + 6\text{H}_2\text{O}

ightarrow 6\text{O}_2 + \text{C}_6\text{H}_{12}\text{O}_6\)) shows:

• how carbon dioxide is split (CO₂ provides C for glucose).
• how oxygen gas is released from water molecules (H₂O splits, O₂ is a product).
• how glucose is built from smaller molecules (CO₂ and H₂O are small; glucose is larger).
• Cannot Be Explained Using This Model of Photosynthesis: The model focuses on the reaction (inputs/outputs), not:
• how the Sun’s energy is stored within carbon dioxide molecules (Sun’s energy is captured, not stored in CO₂).
• how energy is stored within carbohydrates (the model shows glucose formation, not energy storage in carbs).
• how sugars are broken down to release energy (this is cellular respiration, not photosynthesis).

Answer:

Can Be Explained Using This Model of Photosynthesis:

• how carbon dioxide is split
• how oxygen gas is released from water molecules
• how glucose is built from smaller molecules

Cannot Be Explained Using This Model of Photosynthesis:

• how the Sun’s energy is stored within carbon dioxide molecules
• how energy is stored within carbohydrates
• how sugars are broken down to release energy
