Mango, tuna fish , snow leopards are

Options

A. Euryhaline
B. Stenothermal
C. Eurythermal
D. Eurythermal & eurtyhaline

Answer

To determine the classification of mango, tuna fish, and snow leopards based on their tolerance to environmental conditions, we can analyze each term provided in the question.

### Step-by-Step Solution:

1. **Understanding the Terms**:
- **Urehyaline**: This term refers to organisms that can tolerate a wide range of salinity in water. Typically, these organisms can thrive in both freshwater and saltwater environments.
- **Stenothermal**: This term describes organisms that can tolerate only a narrow range of temperatures. They are sensitive to temperature changes and thrive in specific thermal conditions.
- **Urethermal**: This term indicates organisms that can withstand a wide range of temperatures, often found in extreme environments like deserts.
- **Urethermal and Urehyaline**: This combines both terms, suggesting organisms that can tolerate a wide range of both temperature and salinity.

2. **Analyzing Each Organism**:
- **Mango**: This is a terrestrial plant that grows in warm climates and does not tolerate extreme salinity. It is not urehyaline.
- **Tuna Fish**: This species is a marine fish that thrives in specific temperature ranges of ocean waters. It is not urehyaline as it cannot tolerate a wide range of salinity.
- **Snow Leopard**: This is a terrestrial mammal that lives in cold mountainous regions and is adapted to specific temperature ranges. It is not urehyaline.

3. **Evaluating the Options**:
- **Option 1 (Urehyaline)**: Incorrect, as none of the organisms can tolerate a wide range of salinity.
- **Option 2 (Stenothermal)**: Correct, as all three organisms can tolerate only a narrow range of temperatures.
- **Option 3 (Urethermal)**: Incorrect, as these organisms do not thrive in extreme temperature ranges.
- **Option 4 (Urethermal and Urehyaline)**: Incorrect, as they do not fit into either category.

4. **Conclusion**: The correct classification for mango, tuna fish, and snow leopards is that they are **stenothermal**, as they can only tolerate a narrow range of temperatures.

### Final Answer:
Mango, tuna fish, and snow leopards are **stenothermal** organisms.
