Which of the following raw material is available in the air for photosynthesis ?

Options

A. Oxygen
B. Carbon dioxide
C. Nitrogen
D. Hydrogen

Answer

**Step-by-Step Solution:**

1. **Understanding Photosynthesis**: Photosynthesis is the process by which green plants convert light energy into chemical energy, using raw materials to produce glucose and oxygen.

2. **Identifying Raw Materials**: The main raw materials required for photosynthesis are:
- Carbon Dioxide (CO2)
- Water (H2O)
- Sunlight

3. **Source of Raw Materials**:
- **Carbon Dioxide**: This gas is present in the air and is absorbed by plants through tiny openings in their leaves called stomata.
- **Water**: This is absorbed by the roots of the plants from the soil.
- **Sunlight**: This is captured by the chlorophyll, the green pigment in plants.

4. **Determining the Raw Material Available in Air**: Among the raw materials listed, the one that is available in the air is Carbon Dioxide.

5. **Conclusion**: Therefore, the correct answer to the question "Which of the following raw material is available in the air for photosynthesis?" is Carbon Dioxide.

**Final Answer**: Carbon Dioxide (CO2) is the raw material available in the air for photosynthesis.
