Which type of population interaction is found between clown fish and sea anemone?

Options

A. Broad parasitism
B. Parasitism
C. Mutualism
D. Commensalism

Explanation

### Step-by-Step Solution:

1. **Identify the Organisms**: The question involves two organisms: the clownfish and the sea anemone.

2. **Understand Their Relationship**: The clownfish lives among the tentacles of the sea anemone. The tentacles of the sea anemone are stinging and can be harmful to other fish, but the clownfish is immune to these stings.

3. **Analyze the Benefits**: The clownfish benefits from this relationship by gaining protection from predators due to the stinging tentacles of the sea anemone. The clownfish can hide among the tentacles, which deters other fish from attacking it.

4. **Assess the Impact on Sea Anemone**: The sea anemone does not gain any significant benefit from the clownfish residing in its tentacles. It neither suffers nor gains from this interaction, indicating a neutral effect.

5. **Classify the Interaction**: Based on the analysis, the interaction between the clownfish and the sea anemone is one where one organism benefits (the clownfish) and the other is neither helped nor harmed (the sea anemone). This type of relationship is classified as **commensalism**.

6. **Conclusion**: Therefore, the type of population interaction found between clownfish and sea anemone is **commensalism**.
