Options

B. `-ve,` O interaction
C. `+ve, -ve` interaction
D. `+ve , +ve` interaction

Answer

To solve the question, we need to analyze the types of interactions between species in ecology, specifically focusing on parasitism and competition.

### Step-by-Step Solution:

1. **Understanding Parasitism**:
- Parasitism is an interaction where one species (the parasite) benefits at the expense of another species (the host).
- In this relationship, the parasite derives nutrients and shelter from the host, which is harmed in the process.
- Therefore, parasitism is classified as a positive-negative interaction: the parasite benefits (+) while the host is harmed (-).

2. **Understanding Competition**:
- Competition occurs when two or more organisms vie for the same limited resources, such as food, space, or light.
- In this interaction, both species are negatively affected because they are competing for resources that are insufficient for both.
- As a result, competition reduces the growth, reproduction, and survival of both competing organisms.

3. **Classification of Competition**:
- Since both organisms involved in competition are harmed due to resource limitation, this interaction is classified as negative-negative.
- Thus, in competition, both species experience negative outcomes (-) due to their interaction.

4. **Final Conclusion**:
- Given that parasitism is a positive-negative interaction, competition is classified as a negative-negative interaction.

### Answer:
If parasitism is an example of a positive-negative interaction, then competition is an example of a negative-negative interaction.
