Answer

### Step-by-Step Solution:

1. **Identify the Organisms**: The question lists five organisms: Laminaria, Ectocarpus, Dictyota, Sargassum, and Fucus.

2. **Classify the Organisms**: To classify these organisms, we need to determine which group of algae they belong to. Algae are primarily classified into three main classes:
- Red Algae (Rhodophyceae)
- Brown Algae (Phaeophyceae)
- Green Algae (Chlorophyceae)

3. **Determine the Class of Each Organism**:
- **Laminaria**: This is a type of brown algae.
- **Ectocarpus**: Also classified as brown algae.
- **Dictyota**: This organism is part of the brown algae group.
- **Sargassum**: Another member of brown algae.
- **Fucus**: This is also classified as brown algae.

4. **Conclusion**: All the listed organisms (Laminaria, Ectocarpus, Dictyota, Sargassum, and Fucus) belong to the class of **Brown Algae (Phaeophyceae)**.

### Final Answer:
Laminaria, Ectocarpus, Dictyota, Sargassum, and Fucus are examples of **Brown Algae (Phaeophyceae)**.
