Photic zone lies upto the depth of

Options

A. 10M
B. 100M
C. 150M
D. 200M

Answer

**Step-by-Step Solution:**

1. **Understanding the Zones of Water Bodies**: Water bodies are divided into different zones based on the penetration of light. The three main zones are the photic zone, the aphotic zone, and the abyssal zone.

2. **Identifying the Photic Zone**: The photic zone is the uppermost layer of a water body where sunlight penetrates sufficiently to support photosynthesis. This zone is crucial for aquatic life as it is where most of the primary production occurs.

3. **Determining the Depth of the Photic Zone**: The depth of the photic zone is generally estimated to be around 200 meters. This is the maximum depth at which light can penetrate sufficiently for photosynthesis to occur.

4. **Comparing with Other Zones**: Below the photic zone lies the aphotic zone, where light penetration is significantly reduced (less than 200 meters), and further down is the abyssal zone, which is found at depths greater than 10,000 meters and is completely dark.

5. **Conclusion**: Based on the information provided, the depth of the photic zone is confirmed to be 200 meters.

**Final Answer**: The photic zone lies up to a depth of 200 meters.
