The percentage of light energy utilized for photosynthesis by higher plants is

Options

A. 100
B. 50
C. 10
D. 1-2.

Answer

To determine the percentage of light energy utilized for photosynthesis by higher plants, we can follow these steps:

### Step 1: Understand Photosynthesis
Photosynthesis is the process by which plants convert light energy into chemical energy, using sunlight, carbon dioxide, and water to produce glucose and oxygen.

### Step 2: Identify the Range of Light Energy Utilization
Research indicates that during photosynthesis, higher plants utilize only a small fraction of the light energy that reaches them. This is typically in the range of 1 to 4 percent.

### Step 3: Analyze the Options
Given the options: 150, 10, 1 to 2 percent, we need to identify which of these aligns with the known range of light energy utilization.

### Step 4: Compare Options with Known Data
- **150%**: This option is not feasible as it exceeds 100%.
- **10%**: While this is a significant amount, it is still higher than the typical range.
- **1 to 2%**: This option falls within the known range of 1 to 4 percent.

### Step 5: Conclusion
Based on the analysis, the percentage of light energy utilized for photosynthesis by higher plants is approximately **1 to 2 percent**.

### Final Answer
**1 to 2 percent**
