Options

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

Answer

To solve the question, "An interaction between two individuals where one is benefitted while the other is neither benefitted nor harmed is called as," we can follow these steps:

### Step-by-Step Solution:

1. **Understand the Types of Interactions**:
- We need to identify the different types of interactions between organisms. The options given are:
- Commensalism
- Mutualism
- Predation
- Emensalism

2. **Analyze Each Interaction**:
- **Predation**: This interaction involves one organism (the predator) benefiting at the expense of another (the prey). Since the prey is harmed, this option can be eliminated.
- **Mutualism**: In mutualism, both organisms benefit from the interaction. Since the question specifies that only one organism benefits, we can eliminate this option as well.
- **Emensalism**: This interaction involves one organism being harmed while the other remains unaffected. This is the opposite of what we are looking for, so we can eliminate this option too.

3. **Identify the Correct Interaction**:
- **Commensalism**: In this interaction, one organism benefits while the other is neither helped nor harmed. For example, an orchid growing on a tree benefits from the tree by obtaining nutrients and water, while the tree remains unaffected. This matches the description given in the question.

4. **Conclusion**:
- Based on the analysis, the correct answer to the question is **Commensalism**.

### Final Answer:
The interaction between two individuals where one is benefitted while the other is neither benefitted nor harmed is called **Commensalism**.
