The pH range most conducive for life of freshwater plants and animals is

Options

A. 6.5-7.5
B. 2.0-3.5
C. 3.5-5.0
D. 9.0-10.5

Explanation

To determine the pH range most conducive for the life of freshwater plants and animals, we can follow these steps:

### Step-by-Step Solution:

1. **Understanding pH Levels**:
- pH is a measure of how acidic or basic a solution is. It ranges from 0 to 14.
- A pH of 7 is considered neutral. Values below 7 indicate acidity, while values above 7 indicate basicity.

2. **Identifying the pH Range**:
- Freshwater ecosystems require a specific pH range for optimal health and survival of plants and animals.
- Generally, the pH level that supports life in freshwater environments should be close to neutral.

3. **Determining the Optimal pH Range**:
- Research and studies indicate that the optimal pH range for freshwater plants and animals is between 6.5 and 7.5.
- This range is slightly acidic to neutral, which is ideal for most aquatic life.

4. **Conclusion**:
- Therefore, the pH range most conducive for the life of freshwater plants and animals is **6.5 to 7.5**.

### Final Answer:
The pH range most conducive for life of freshwater plants and animals is **6.5 to 7.5**.
