D. 10,000 m below sea level to about 10,000 m above the sea level.

Answer

To answer the question regarding the extent of the biosphere, we can follow these steps:

### Step-by-Step Solution:

1. **Understanding the Biosphere**: The biosphere is defined as the part of Earth where life exists. It includes all living organisms and their interactions with the environment.

2. **Identifying the Range of the Biosphere**: The biosphere extends vertically from the deepest parts of the ocean to the highest points on land. This means we need to consider both below sea level and above sea level.

3. **Considering the Depths and Heights**:
- The biosphere reaches down to about 6,000 meters below sea level, which includes the deepest oceanic trenches.
- It also extends up to about 6,000 meters above sea level, which encompasses the highest mountain peaks.

4. **Conclusion**: Based on this understanding, the correct answer is that the biosphere extends from about 6,000 meters below sea level to about 6,000 meters above sea level.

### Final Answer:
The biosphere extends from about 6,000 meters below sea level to about 6,000 meters above sea level.
