Small fish get stuck near the bollom of a shark and derives its nutrition from it. This kind of association is called

Options

A. Antibiosis
B. Commensalism
C. Predation
D. Parasitism

Answer

To solve the question regarding the type of association between a small fish and a shark, we will analyze the options provided and determine the correct answer step by step.

### Step-by-Step Solution:

1. **Understand the Question**: The question states that a small fish gets stuck near the bottom of a shark and derives its nutrition from it. We need to identify the type of association this represents.

2. **Identify the Options**: The options given are:
- Antibiosis
- Commensalism
- Predation
- Parasitism

3. **Define Each Association**:
- **Antibiosis**: This is a type of antagonistic association where at least one organism is negatively affected. For example, a host plant may be harmed by a pathogen.
- **Commensalism**: In this association, one organism benefits while the other remains unaffected. The benefiting organism gains something without harming or helping the other.
- **Predation**: This involves two species where one (the predator) benefits by consuming the other (the prey), which is negatively affected.
- **Parasitism**: In this relationship, one organism (the parasite) benefits at the expense of the other (the host), which may be negatively affected or remain neutral.

4. **Analyze the Given Scenario**: In the scenario, the small fish is deriving nutrition from the shark. The shark does not seem to be negatively affected by the presence of the small fish; it remains neutral. Therefore, the small fish benefits while the shark is unaffected.

5. **Determine the Correct Association**: Since the small fish benefits and the shark is unaffected, this scenario fits the definition of **commensalism**.

6. **Select the Answer**: The correct answer to the question is **commensalism**.

### Final Answer:
The type of association described in the question is called **commensalism**.
