Solution

Photosynthesis:
Photosynthesis is the process of conversion of light energy (sunlight) into chemical energy (food) by using carbon dioxide, water and chlorophyll.
6 CO₂ + 12 H₂O → Glucose (C₆H₁₂O₆) + 6 H₂O + 6 O₂
Oxygen is released from the plant as a by-product of photosynthesis.
Therefore, carbon dioxide is used as a raw material and gets utilized in the process.
Final answer: Carbon dioxide is necessary for photosynthesis as it the major raw material used to form glucose.
