chemical break down
The tongue is involved in both mechanical and chemical digestion. It helps break down food into smaller pieces through chewing (mechanical digestion) and it also helps mix food with saliva, which contains enzymes that start breaking down carbohydrates (chemical digestion).
Mechanical digestion must come first because it helps break down food

Yes, both chemical and mechanical digestion break down food into smaller units.

chemical digestion is breaking down with saliva, and mechanical digestion is chewing...(break down with chew!):):P
Pepsin =)
They both break down food. Mechanical digestion literally breaks it down by grinding it. Whereas chemical digestion uses amylase (saliva that contains an enzyme) To break down the foods from starch to simple sugars.

The two main phases of the digestive process are the mechanical digestion phase, which involves physically breaking down food through chewing and the movement of the stomach and intestines; and the chemical digestion phase, where enzymes and stomach acids break down food into smaller molecules that can be absorbed by the body.
What mechanical and chemical weathering have in common is they both break rocks down into smaller and smaller pieces. Eventually the weathered rock will be eroded.
