Organisms that can tolerate a wide range of salt concentration are ternnned as

Options

A. Stenosaline
B. Stenohaline
C. Euryhaline
D. Eurythermal

Answer

To answer the question regarding organisms that can tolerate a wide range of salt concentration, we can follow these steps:

### Step-by-Step Solution:

1. **Understanding the Terms**:
- First, we need to understand the terminology related to organisms and their tolerance to salinity. There are different terms used to classify organisms based on their salt tolerance.

2. **Identify the Options**:
- The options given are:
1. Stenosaline
2. Stenohaline
3. Urehaline
4. Urethermal

3. **Define the Terms**:
- **Stenohaline**: These organisms can only tolerate a narrow range of salinity. They are sensitive to changes in salt concentration.
- **Urehaline**: These organisms can tolerate a wide range of salinity. They are adaptable to varying salt concentrations.
- **Stenosaline**: This term is not commonly used in biological contexts.
- **Urethermal**: This term relates to temperature tolerance rather than salinity.

4. **Selecting the Correct Answer**:
- Based on the definitions, organisms that can tolerate a wide range of salt concentration are referred to as **Urehaline**. Therefore, the correct answer to the question is option 3, Urehaline.

5. **Example of Urehaline Organisms**:
- An example of a urehaline organism is the Fusilla fish, which can survive in various salinity levels.

### Final Answer:
The organisms that can tolerate a wide range of salt concentration are termed as **Urehaline**.
