Question 1 Report

The excretory product of some reptiles, birds and insects is

Answer Details
The excretory product of some reptiles, birds and insects is uric acid. Uric acid is a waste product that is produced when the body breaks down food. Unlike mammals, which excrete waste products as urine, reptiles, birds and insects excrete waste products as uric acid. This is because they have a more efficient system for conserving water, which is important for species living in arid environments. The uric acid is solid and is excreted as white, crystalline deposits that can be seen in the feces of these animals. This type of excretion is also known as "dry excretion".
