Chemical weathering is when chemicals such as chemicals excreted from plants wear away at the earth's surface. Mechanical weathering is when natural forces wear away at the earth's surface such as rock.
a mechanical illustration is a SMALL sketch, like the size of a thumbnail. Leonardo daVinci used these
The type of energy which is stored in a battery is electrical.
Different parts of digestive system .
It's the chemical breakdown of food into simpler compounds. Proteins are broken down to amino acids, carbohydrates are broken down to simple sugars, and fats are broken down to fatty acids and glycerol. Chemical digestion does begin in the mouth. Salivary amylase starts hydrolyzing starch the second you put in into your mouth. BUT, the vast majority of chemical digestion takes place in the duodenum and jejunum portions of the small intestine.
I consider that this is a physical process.
The small intestine completes the process of chemical digestion.

chemical break down
Yes, in part. Chemical digestion occurs in the mouth (saliva), stomach (gastric acid) and small intestine. The nutrients are mostly absorbed in the walls (lining) of the small intestine.
what is responsible for chemical digestion in earthworms
The mouth is the beginning of both mechanical and chemical digestion. Chewing breaks the food into smaller pieces and the saliva wets the food but also adds an enzyme called amylase that begins the digestion of carbohydrates.
digestion
Chemical and mechanical ingestion take place in the mouth. Chemical and mechanical digestion also take place in the stomach. Chemical digestion takes place in the small intestine.Ingestion, digestion then absorption.In the mouth, both chemical digestion and mechanical digestion happen. The mechanical part is your teeth crushing the food into smaller pieces. The chemical part is when the salivary glands give off a special fluid that contains enzymes. When food enters the stomach, an enzyme is released that helps to digest food chemicaly. The muscles in the stomach also digest food mechanicly. Lastly, the small intestine completes the chemical and mechanical digestion of food. The small intestine takes out all the useful matirial and sends it to the cells as tiny molecules that the cells use in cellular resparation.Baisicly, they all use chemical and mechanical digestion.
mechanical digestion is with your teeth , chemical digestion is in your stomach and small intestine.
