Explain the compensation point.

Explanation

### Step-by-Step Solution:

1. **Definition of Compensation Point**: The compensation point is the specific level of light intensity or atmospheric CO2 concentration at which the rate of photosynthesis in a plant equals the rate of respiration. At this point, there is no net gain or loss of carbon dioxide in the plant.

2. **Understanding Photosynthesis and Respiration**:
- **Photosynthesis** is the process by which plants convert light energy into chemical energy, using carbon dioxide (CO2) and water (H2O) to produce glucose and oxygen (O2).
- **Respiration** is the process by which plants break down glucose to release energy, consuming oxygen and producing carbon dioxide and water as byproducts.
