Find the wrong match.

Options

A. Endotherm - Warm blooded or homeotherms
B. Ectotherm - Cold blooded or Poikilotherms
C. Stenohaline - Tolerates wide range of salinites
D. Euryhaline - Tolerates wide range of salinites

Answer

To solve the question "Find the wrong match," we need to analyze the provided pairs and determine which one is incorrectly matched.

### Step-by-Step Solution:

1. **Identify the first pair: Endotherm - Warm-blooded and Homeotherm**
- Endotherms are organisms that can regulate their body temperature internally, which means they are indeed warm-blooded and maintain a constant body temperature (homeotherm).
- **Conclusion:** This pair is correctly matched.

2. **Identify the second pair: Ectotherm - Cold-blooded and Poikilotherm**
- Ectotherms are organisms that rely on external environmental conditions to regulate their body temperature, and they are referred to as cold-blooded. They do not maintain a constant body temperature, which makes them poikilotherms.
- **Conclusion:** This pair is also correctly matched.

3. **Identify the third pair: Stenohaline - Tolerates a wide range of salinities**
- Stenohaline organisms can only tolerate a narrow range of salinities. They are not able to adapt to wide fluctuations in salinity levels.
- **Conclusion:** This pair is incorrectly matched.

4. **Identify the fourth pair: Euryhaline - Tolerates a wide range of salinities**
- Euryhaline organisms can tolerate a wide range of salinities, which means they can survive in both freshwater and saltwater environments.
- **Conclusion:** This pair is correctly matched.

### Final Answer:
The wrong match is **Stenohaline - Tolerates wide range of salinities.**
