The waste product of insects is?

A. uric acid
B. urine
C. Mucilage
D. sweat

Correct Answer:

Option A – uric acid

Explanation

Most terrestrial insects produce uric acid as their main nitrogenous waste product. Uric acid is a relatively non- toxic and highly insoluble waste product.

Therefore, it can crystallize out of solution, and may be either retained in the body, or eliminated as a solid waste material with little water loss.
