Interaction where one species is benefited and other is neither nor harmed is called :

Options

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

Answer

To solve the question regarding the type of interaction where one species benefits while the other is neither harmed nor benefited, we can follow these steps:

### Step-by-Step Solution:

1. **Understand the Types of Interactions**: We need to identify the different types of species interactions. The four main types are:
- **Parasitism**: One species benefits at the expense of the other (one is harmed).
- **Amensalism**: One species is harmed while the other is unaffected.
- **Commensalism**: One species benefits while the other is neither helped nor harmed.
- **Mutualism**: Both species benefit from the interaction.

2. **Analyze Each Interaction**:
- **Parasitism**: In this interaction, the parasite benefits while the host is harmed. This does not fit our requirement.
- **Amensalism**: Here, one species is harmed, and the other is unaffected. This also does not fit our requirement.
- **Commensalism**: In this interaction, one species benefits, and the other is neither harmed nor benefited. This fits our requirement.
- **Mutualism**: In mutualism, both species benefit, which is not what we are looking for.

3. **Identify the Correct Answer**: Based on the analysis, the interaction where one species benefits and the other is neither harmed nor benefited is **Commensalism**.

4. **Final Answer**: The correct answer is **Commensalism**.
