Photosynthetic organisms occur at different depths in the ocean. Do they receive qualitatively and quantitatively the same light ? How do they adapt to carry out photosynthesis under these conditions.

Explanation

### Step-by-Step Solution:

1. **Understanding Light in the Ocean**:
- Photosynthetic organisms, such as algae, are found at various depths in the ocean. The quality and quantity of light they receive differ significantly based on their depth.
- As light penetrates water, it is absorbed and scattered, leading to a decrease in intensity and a change in the spectrum of light available at greater depths.

2. **Qualitative and Quantitative Differences**:
- **Quantitative Differences**: At shallower depths, organisms receive more light (both in intensity and duration) compared to those at greater depths, where light is less intense and available for shorter periods.
