Excretion is the process of eliminating waste products of metabolism and other non-useful materials. It is an essential process in all forms of life.

Excretion is when a living thing get rid.

There are 6 types of animal that do different Excretion or could be the same.

Types of animals: Amphibians, Birds, Fish, Insects, Mammals and Reptiles.

Excretion:H2O-H2O Is a liquid. -Excretion is a

solid.

Similarities: without h2o excretory system can’t work, because the water makes the excretion have a better digestion.
