Organisms tolerant to wide range of salinities are termed

Options

A. 1)Stenohaline
B. 2)Stenothermal
C. 3)Euryhaline
D. 4)Eurythermal

Answer

To solve the question "Organisms tolerant to wide range of salinities are termed," we will analyze the options provided and determine which one correctly describes such organisms.

### Step-by-Step Solution:

1. **Understanding the Question**: The question asks for the term used to describe organisms that can tolerate a wide range of salinities. Salinity refers to the concentration of dissolved salts in water.

2. **Analyzing the Options**:
- **Option 1: Tenohaline**: This term refers to organisms that are restricted to a narrow range of salinity. Therefore, this option is incorrect.
- **Option 2: Tenothermal**: This term refers to organisms that require a narrow range of temperature to survive. This is unrelated to salinity, making this option incorrect as well.
- **Option 3: Urehaline**: This term describes organisms that can tolerate a wide range of salinities. This is the correct option since it directly addresses the question.
- **Option 4: Urethermal**: This term refers to organisms that can tolerate a wide range of temperatures, which is not related to salinity. Thus, this option is also incorrect.

3. **Conclusion**: Based on the analysis of the options, the correct answer is **Urehaline**, as it specifically refers to organisms that can tolerate a wide range of salinities.

### Final Answer:
The organisms tolerant to a wide range of salinities are termed **Urehaline**.
