Question

Which of the following is excretory material in birds?

• A. Ammonia
• B. Urea
• C. Uric acid
• D. Creatinine

Hint:

The excretion of uric acid helps birds conserve water, a critical adaptation for survival in environments with limited water resources.

Answer 1

The Correct Option is C

Birds excrete uric acid as their primary nitrogenous waste product. Unlike mammals, which excrete urea, birds excrete uric acid in a semi-solid form to conserve water, which is crucial in their often arid habitats. Thus, the correct answer is Uric acid.
