The phenomenon of interaction between the member of two different species where one organisam is being benefitted without affecting the others is

Options

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

Answer

To solve the question regarding the interaction between members of two different species where one organism benefits without affecting the other, we can follow these steps:

### Step-by-Step Solution:

1. **Understand the Types of Interactions**:
- Interactions between species can be classified into several categories, including mutualism, commensalism, predation, and amensalism. It is essential to understand what each term means.

2. **Define Amensalism**:
- In amensalism, one species is harmed while the other is unaffected. This does not fit our criteria since we need one organism to benefit.

3. **Define Commensalism**:
- In commensalism, one organism benefits while the other is neither helped nor harmed. This aligns perfectly with the question's requirement.

4. **Define Mutualism**:
- In mutualism, both organisms benefit from the interaction. This does not fit our criteria since we need one organism to benefit and the other to be unaffected.

5. **Define Predation**:
- In predation, one organism (the predator) benefits by feeding on another organism (the prey), which is harmed. This does not fit our criteria since one organism is harmed.

6. **Conclusion**:
- Based on the definitions and analysis, the correct answer to the question is **commensalism**, where one organism benefits without affecting the other.

### Final Answer:
The phenomenon of interaction between the members of two different species where one organism is being benefitted without affecting the other is **commensalism**.
