Identify the correct matching pair

Options

A. fish - uricotelic
B. man - ureotelic
C. bird - ammonotelic
D. frog - uricotelic

Answer

To solve the question "Identify the correct matching pair," we need to analyze the definitions and examples of the terms ammonotelic, ureotelic, and uricotelic.

### Step-by-Step Solution:

1. **Understand the Terms**:
- **Ammonotelic**: Organisms that excrete nitrogenous waste primarily in the form of ammonia.
- **Ureotelic**: Organisms that excrete nitrogenous waste primarily in the form of urea.
- **Uricotelic**: Organisms that excrete nitrogenous waste primarily in the form of uric acid.

2. **Identify Examples**:
- **Ammonotelic Organisms**: Examples include aquatic animals like fish and tadpoles.
- **Ureotelic Organisms**: Examples include mammals, some bony fishes, and adult amphibians like frogs.
- **Uricotelic Organisms**: Examples include reptiles such as snakes and lizards.

3. **Analyze the Options**:
- Option 1: Ureotelic organisms are fishes (Incorrect, as some fishes are ureotelic but not all).
- Option 2: Ureotelic organisms are man (Correct, as humans are ureotelic).
- Option 3: Ammonotelic organisms are aquatic fishes (Incorrect, as this is too broad; not all fishes are ammonotelic).
- Option 4: Uricotelic organisms are frogs (Incorrect, frogs are ureotelic, not uricotelic).

4. **Select the Correct Pair**:
- The only correct matching pair is: **Ureotelic organisms are man**.

### Final Answer:
The correct matching pair is: **Ureotelic organisms are man**.
