Solution

Excretion:
The process by which the waste products that are harmful to the body are removed from the body is known as excretion.
Types:
Based on the type of excretory product released by organisms, they are divided into three main categories namely - ammonotelic, ureotelic, and uricotelic.
Ammonotelic organisms are those that excrete ammonia as their waste product.
Ureotelic organisms are those that excrete urea as their waste product.
Uricotelic organisms are those that excrete uric acid as their waste product.
The differences among these organisms and their modes of excretion are given below:
Ammonotelic Ureotelic Uricotelic
Excretory product The organisms that release ammonia as their excretory product are called ammonotelic organisms. The organisms that release urea as their excretory product are called ureotelic organisms. The organisms that release uric acid as their excretory product are called uricotelic organisms.
Process of excretion The process by which ammonotelic organisms release their waste products is known as ammonotelism. The process by which ureotelic organisms release their waste products is known as ureotelism. The process by which uricotelic organisms release their waste products is known as uricotelism.
