Which element is responsible for providing carbon dioxide to plants for photosynthesis?

Options

A. Air
B. Land
C. Water
D. Sunlight

Explanation

**Step-by-Step Solution:**

1. **Understanding Photosynthesis**:
- Photosynthesis is the process by which plants convert light energy into chemical energy, using carbon dioxide (CO2) and water (H2O) to produce glucose (food) and oxygen (O2).

2. **Identifying the Components Needed for Photosynthesis**:
- The essential components for photosynthesis include carbon dioxide, water, sunlight, and chlorophyll.

3. **Source of Carbon Dioxide**:
- Carbon dioxide is a key ingredient in photosynthesis. It is primarily obtained from the air.

4. **Composition of Air**:
- Air is composed of several gases, including approximately 78% nitrogen, 21% oxygen, and about 0.3% carbon dioxide. This small percentage of carbon dioxide is sufficient for plants to carry out photosynthesis.

5. **Conclusion**:
- Since carbon dioxide is found in the air, the element responsible for providing carbon dioxide to plants for photosynthesis is **air**.

**Final Answer**: The element responsible for providing carbon dioxide to plants for photosynthesis is **air**.
