Options

A. are found only in fresh water
B. are the chief producers in the oceans
C. are microscopic and float actively in water current
D. are only parasitic

Answer

**Step-by-Step Solution:**

1. **Understanding Chrysophytes**: Chrysophytes are a group of protists that include organisms such as diatoms and golden algae. They are primarily known for their photosynthetic capabilities.

2. **Analyzing the Options**:
- **Option 1**: "Found only in fresh water" - This is incorrect. Chrysophytes can be found in both fresh water and marine environments.
- **Option 2**: "The chief producers in the oceans" - This is correct. Diatoms, which are part of the chrysophytes group, are significant producers in marine ecosystems.
- **Option 3**: "Microscopic and float actively in water" - This is incorrect. While diatoms are microscopic, they float passively in water currents rather than actively swimming.
- **Option 4**: "Content are only parasitic" - This is incorrect. Chrysophytes are primarily autotrophic, meaning they produce their own food through photosynthesis, and are not parasitic.

3. **Conclusion**: The correct statement regarding chrysophytes is that they are the chief producers in the oceans due to their abundance and photosynthetic nature.

**Final Answer**: The members of the group chrysophytes are the chief producers in the oceans.
