Relation between down fish and sea anemone:

Options

A. Mutualism
B. Commensalism
C. Parasitism
D. Amensalism

Answer

**Step-by-Step Solution:**

1. **Identify the Organisms**: The two organisms in question are the Clownfish (Amphiprioninae) and the Sea Anemone (Actiniaria).

2. **Understanding the Relationship**: The relationship between Clownfish and Sea Anemone is primarily one of protection and shelter. Clownfish seek refuge among the tentacles of the Sea Anemone to avoid predators.

3. **Analyzing the Benefits**:
- **Clownfish**: They benefit from the Sea Anemone by gaining protection from predators, as the stinging tentacles of the anemone deter potential threats.
- **Sea Anemone**: The Sea Anemone does not gain any significant benefit or harm from the presence of Clownfish. Thus, it is unaffected by their presence.

4. **Classifying the Relationship**: This type of interaction is classified as **commensalism**. In commensalism, one organism benefits while the other is neither helped nor harmed.

5. **Additional Mutual Benefits**: While the primary relationship is commensalism, there can be mutual benefits as well. For instance, Clownfish can help keep the Sea Anemone clean by removing debris and parasites, and in return, the Sea Anemone provides shelter.

6. **Distinguishing from Other Relationships**:
- **Parasitism**: In parasitism, one organism benefits at the expense of the other, which is not the case here.
- **Amensalism**: In amensalism, one organism is harmed while the other is unaffected, which also does not apply to this relationship.

7. **Conclusion**: Therefore, the relationship between Clownfish and Sea Anemone is best described as commensalism, where Clownfish gain protection and the Sea Anemone remains unaffected.
