Energy contained in plant carbohydrates comes from

Options

A. Minerals
B. `CO_(2)`
C. Proteins
D. Sunlight

Answer

**Step-by-Step Solution:**

1. **Understanding Carbohydrates in Plants**: Carbohydrates, such as glucose, are essential energy sources for plants. They are produced during the process of photosynthesis.

2. **Photosynthesis Process**: The basic equation for photosynthesis can be summarized as:
\[ \text{Carbon Dioxide (CO}_2\text{) + Water (H}_2\text{O) + Light Energy (from Sunlight)} \rightarrow \text{Glucose (C}_6\text{H}_{12}\text{O}_6\text{) + Oxygen (O}_2\text{)} \]
This equation shows that plants take in carbon dioxide and water and, using sunlight, convert these into glucose and oxygen.

3. **Source of Energy**: In the photosynthesis process, the energy required to convert carbon dioxide and water into glucose comes from sunlight. This light energy is captured by chlorophyll in the plant's leaves.

4. **Conclusion**: Therefore, the energy contained in plant carbohydrates is derived from sunlight.

5. **Final Answer**: The correct option is **D) Sunlight**.
