Two species competing for the same resource can avoid competition by choosing different habits. This phenomenon is called

Options

A. Competitive exclusion
B. Competitive fitness
C. Survival of the fittest
D. Resource partitioning

Answer

To solve the question regarding the phenomenon where two species competing for the same resource can avoid competition by choosing different habitats, we will analyze the options provided and identify the correct term.

### Step-by-Step Solution:

1. **Understanding the Question**: The question asks about a phenomenon where two species avoid competition by selecting different habitats while competing for the same resource.

2. **Analyzing the Options**:
- **Option A: Competitive Exclusion**: This theory states that two species competing for the same resources cannot coexist; one will outcompete the other and lead to extinction. This does not describe the avoidance of competition through habitat selection.
- **Option B: Competitive Fitness**: This term refers to the ability of a species to compete for resources. It does not imply habitat selection or avoidance of competition.
- **Option C: Survival of the Fittest**: This concept, introduced by Darwin, suggests that the organisms best adapted to their environment will survive. However, it does not specifically address the avoidance of competition through habitat differentiation.
- **Option D: Resource Partitioning**: This term refers to the division of limited resources among species to reduce competition. It involves species utilizing different habitats or resources, thereby avoiding direct competition.

3. **Identifying the Correct Answer**: Based on the analysis, the correct answer is **Resource Partitioning**. This phenomenon allows species to coexist by utilizing different resources or habitats, thus avoiding competition.

### Final Answer:
The phenomenon where two species competing for the same resource can avoid competition by choosing different habitats is called **Resource Partitioning**.
