Options

A. Positive interaction
B. Negative interaction
C. Neither positive nor negative interaction
D. Symbiotic relationship

Answer

To solve the question regarding competition being a rivalry between two or more organisms for obtaining the same resources, we need to analyze the nature of competition and its implications on interactions between species. Here’s a step-by-step breakdown:

### Step-by-Step Solution:

1. **Understanding Competition**:
- Competition occurs when two or more organisms vie for the same resources, such as food, water, space, or mates. This rivalry can happen within a species (intraspecific competition) or between different species (interspecific competition).

2. **Identifying Types of Interactions**:
- There are various types of interactions in ecology, including positive interactions (mutualism), negative interactions (competition, predation), and neutral interactions.

3. **Analyzing Positive Interaction**:
- Positive interactions, such as mutualism, benefit both species involved. For example, bees pollinating flowers benefit both the bees (food source) and the flowers (reproduction).

4. **Analyzing Negative Interaction**:
- Negative interactions occur when one species benefits at the expense of another. In the case of competition, the fittest organism gains access to the resources, while the less fit organism suffers due to limited resources.

5. **Considering Neutral Interaction**:
- Neutral interactions imply that neither species benefits nor is harmed, which does not apply to competition.

6. **Examining Symbiotic Relationships**:
- Symbiotic relationships involve close interactions between species, where both may benefit (mutualism) or one benefits while the other is harmed (parasitism). However, competition does not fit this definition as it inherently involves a struggle for limited resources.

7. **Conclusion**:
- Given the definitions and implications of these interactions, competition is classified as a negative interaction because it results in one organism benefiting (the fittest) while the other is harmed (the less fit).

### Final Answer:
Competition is a type of **negative interaction**.
