Uric acid is excreted in

Options

A. Frog
B. Rabbit
C. Man
D. Pigeon/Crow

Answer

**Step-by-Step Solution:**

1. **Understanding Nitrogenous Waste**:
- Organisms excrete nitrogenous waste in different forms based on their metabolic processes. The main forms of nitrogenous waste are ammonia, urea, and uric acid.

2. **Identifying Ureotelic Organisms**:
- Ureotelic organisms excrete nitrogenous waste primarily in the form of urea. Examples include frogs, rabbits, and humans. This means that these organisms do not excrete uric acid.

3. **Identifying Uricotelic Organisms**:
- Uricotelic organisms excrete nitrogenous waste in the form of uric acid. This is a more water-efficient way of excretion, which is particularly advantageous for organisms that need to conserve water.

4. **Analyzing the Given Options**:
- The question lists frogs, rabbits, humans, pigeons, and crows.
- From the previous steps, we know that frogs, rabbits, and humans are ureotelic and excrete urea.
- Pigeons and crows, on the other hand, are uricotelic and excrete uric acid.

5. **Conclusion**:
- Therefore, the correct answer to the question "Uric acid is excreted in" is pigeons and crows.

**Final Answer**: Uric acid is excreted in pigeons and crows.
