Answer 2

'Uric acid' is 'excreted' by Pigeon  

Answer:  Option (d)

Explanation:  

• Excretion is a fundamental part of a living being’s mechanism and it is through this process that organisms get rid of the nitrogen created in the body after protein breakdown.
• The 'nitrogen in the body' of mammals is converted to urea and goes out of the body 'through urine'.
• Birds, however, convert it into uric acid and stores in the cloaca and eventually out of the body. Pigeon is a bird, and it also excretes uric acid.
