Ecological amplitude of a species is related to

Options

A. Zones of stress
B. Zone of optimum tolerance range of a factor
C. Area with zones of optimum tolerance ranges of all determining factors
D. None of the above.

Answer

**Step-by-Step Solution:**

1. **Understand Ecological Amplitude**: Ecological amplitude refers to the range of environmental conditions that a species can tolerate. It indicates how well a species can adapt to changes in its environment.

2. **Identify Key Terms**: The question mentions several terms: zone of stress, zone of optimum tolerance range, and area with zone of optimum tolerance ranges of all determining factors. Understanding these terms is crucial.

3. **Define Zones**:
- **Zone of Stress**: This is the range of conditions where a species starts to experience stress and may not thrive.
- **Zone of Optimum Tolerance**: This is the ideal range of conditions where a species can survive and reproduce effectively.

4. **Relate Ecological Amplitude to Tolerance Ranges**: The ecological amplitude is closely related to the zone of optimum tolerance ranges. A species with a wide ecological amplitude can thrive in a broader range of conditions, while a species with a narrow ecological amplitude can only survive in specific conditions.

5. **Consider the Options**: The options provided are:
- Zone of stress
- Zone of optimum tolerance range of a factor
- Area with zone of optimum tolerance ranges of all determining factors
- None of the above

6. **Evaluate the Correct Answer**: The correct answer is the option that encompasses all the factors affecting a species' ecological amplitude. Therefore, the ecological amplitude of a species is best described by the "area with zone of optimum tolerance ranges of all determining factors."

7. **Final Answer**: The ecological amplitude of a species is related to the area with zone of optimum tolerance ranges of all determining factors.
