Resource partitioning ' is an important mechanism which promotes

Options

A. Competitive release
B. Co-existence
C. Competitive exclusion
D. Antibiosis

Answer

**Step-by-Step Solution:**

1. **Understanding Resource Partitioning**: Resource partitioning refers to the way in which different species divide resources to minimize competition. This can involve using different resources or using the same resource in different ways or at different times.

2. **Purpose of Resource Partitioning**: The main purpose of resource partitioning is to reduce competition among species. By dividing resources, species can coexist more effectively without outcompeting one another.

3. **Identifying the Mechanisms Promoted by Resource Partitioning**:
- **Competitive Release**: This occurs when a species expands its niche due to the removal of a competitor. This is not directly promoted by resource partitioning.
- **Coexistence**: Resource partitioning promotes coexistence by allowing multiple species to utilize different resources or the same resource in different ways, thus reducing direct competition.
- **Competitive Exclusion**: This principle states that two species competing for the same resource cannot coexist; one will outcompete the other. Resource partitioning helps avoid this scenario.
- **Antibiosis**: This refers to a relationship where one organism produces a substance that is harmful to another. This is not directly related to resource partitioning.

4. **Conclusion**: Among the options provided, the mechanism that is most directly promoted by resource partitioning is **coexistence**.

**Final Answer**: Resource partitioning is an important mechanism which promotes **coexistence**.
