alleryBirds, reptiles, and insects are classified as URICOTELIC because they primarily excrete:
AAmmonia (highly toxic, common in fish)
BUric acid (low toxicity, very little water)
CUrea (moderately toxic, common in mammals)
DCreatinine (a muscle breakdown product)
Answer & Solution
Correct answer: B. Uric acid (low toxicity, very little water)
Uricotelic animals excrete URIC ACID (insoluble paste, low toxicity, requires minimal water).
Suits flying birds + desert-dwelling reptiles.
Aquatic = ammonotelic; mammals = ureotelic.
