$\huge\red{\underline{\boxed{Answer :-}}}$

• Excretion is a process in which metabolic waste is eliminated from an organism. In vertebrates this is primarily carried out by the lungs, kidneys, and skin. The excretory organs remove these wastes. This process of removal of metabolic waste from the body is known as excretion.

• Feces is the solid or semi-solid remains of food that was not digested in the small intestine, and has been broken down by bacteria in the large intestine. Feces contains a relatively small amount of metabolic waste products such as bacterially altered bilirubin, and dead epithelial cells from the lining of the gut.
