The relationship between two species in which one is inhibited or harmed by the presence of the other is :

Options

A. commensalism
B. amensalism
C. mutualism
D. symbiosis

Answer

To solve the question regarding the relationship between two species where one is inhibited or harmed by the presence of the other, we can follow these steps:

### Step-by-Step Solution:

1. **Understand the Types of Relationships**: Begin by identifying the different types of species interactions. The main types include commensalism, mutualism, symbiosis, and amensalism.

2. **Define Commensalism**: In commensalism, one species benefits while the other is neither helped nor harmed. An example is orchids growing on trees, where the orchids benefit from the tree without affecting it.

3. **Define Mutualism**: In mutualism, both species benefit from the interaction. For instance, bees pollinating flowers is a mutualistic relationship since both parties gain from the interaction.

4. **Define Amensalism**: Amensalism is a relationship where one species is inhibited or harmed by the presence of another species, while the second species remains unaffected. An example of this could be a large tree shading smaller plants, which may inhibit their growth.

5. **Identify the Correct Answer**: Given the definitions, the relationship described in the question—where one species is harmed or inhibited by another—is best described as amensalism.

6. **Choose the Correct Option**: Based on the definitions and the analysis, the correct answer to the question is amensalism.

### Final Answer:
The relationship between two species in which one is inhibited or harmed by the presence of the other is called **amensalism**.
