Gause's Competitive exclusion principle states that :

Options

A. Two unrelated genus competing for the same resources cannot co-exist indefinitely and Competitively superior one will get eliminated eventually
B. Two closed related species competing for the same resources cannot co-exist indefinitely and Competitively inferior one will get eliminated eventually
C. Two unrelated species competing for the same workshops resources can co-exist indefinitely and can grow
D. Two closely related species competing for the same resources cannot co - exist indefinitely but can grow together

Answer

### Step-by-Step Solution:

1. **Understanding Gause's Competitive Exclusion Principle**:
- The principle states that two species that compete for the exact same resources cannot coexist indefinitely. One species will outcompete the other, leading to the extinction of the less competitive species.

2. **Identifying Key Terms**:
- **Closely Related Species**: The principle specifically applies to species that are closely related and have similar ecological niches.
- **Competing for the Same Resources**: This refers to the necessity of resources such as food, water, and habitat for survival.
- **Elimination of the Inferior Competitor**: The species that is less efficient in utilizing the resources will eventually be eliminated.

3. **Analyzing the Options**:
- **Option 1**: States that unrelated species can coexist indefinitely. This is incorrect as the principle focuses on closely related species.
- **Option 2**: Correctly states that closely related species competing for the same resources cannot coexist indefinitely, and the competitively inferior one will be eliminated.
- **Option 3**: Suggests that unrelated species can coexist indefinitely, which is also incorrect.
- **Option 4**: Claims that closely related species can grow together while competing for the same resources, which contradicts the principle.

4. **Conclusion**:
- The correct interpretation of Gause's Competitive Exclusion Principle is that closely related species competing for the same resources cannot coexist indefinitely, and the one that is less competitive will be eliminated.
