• A. carbon dioxide
• B. oxygen

Answer 1

Photosynthesis:

1. The process by which green plants make their own food with the help of carbon dioxide, water in the presence of sunlight and chlorophyll is known as photosynthesis.
2. During the process of photosynthesis, leaves give out oxygen and absorb carbon dioxide that supports different life forms on the earth.
3. The overall chemical equation of photosynthesis is:

6CO₂ + 6H₂O → C₆H₁₂O₆ + 6O_{2
(Carbon dioxide) (water) (glucose) (oxygen)}

Final answer: During photosynthesis, plants take in carbon dioxide and release oxygen.
