what percentage of PAR is is captured by plants ?

Options

A. more than 50%
B. 0.5
C. 20 to 40%
D. 2 to 10%

Answer

To determine the percentage of Photosynthetically Active Radiation (PAR) that is captured by plants, we can follow these steps:

### Step-by-Step Solution:

1. **Understand the Concept of PAR**:
- Photosynthetically Active Radiation (PAR) refers to the range of light wavelengths (400 to 700 nm) that plants use for photosynthesis.

2. **Identify the Percentage Captured**:
- According to the information provided, plants capture a specific percentage of PAR for the synthesis of organic matter.

3. **Review the Given Options**:
- The options provided are:
- More than 50%
- 0.5%
- 20-40%
- 2-10%

4. **Analyze the Information**:
- The transcript states that plants capture about 1-5% of incident solar energy, which translates to approximately 2-10% of PAR.

5. **Select the Correct Answer**:
- Based on the analysis, the correct percentage of PAR captured by plants is **2-10%**.

### Final Answer:
The percentage of PAR captured by plants is **2-10%**.
