Question

The primary nitrogenous waste excreted by birds is
A)ammonia.
B)nitrate.
C)nitrite.
D)urea.
E)uric acid.

Accepted Answer

Birds excrete uric acid as their primary nitrogenous waste. This is because uric acid is insoluble in water and can be excreted in a semisolid or solid form, which is useful for birds as they do not have a urinary bladder to store urine. Additionally, excreting uric acid requires less water than excreting other nitrogenous wastes like ammonia or urea, which is important for birds that live in arid environments.
