The organs, which do both mechanical and chemical digestion are the mouth and the stomach. Both these organs are the components of the digestive tract. In the mouth, the mechanical digestion occurs through chewing, on the other hand, the chemical digestion begins in the mouth as a consequence of the enzymes lipase and amylase.
In the stomach, the mechanical digestion takes place by churning, and the chemical digestion is performed by the enzyme protease.
The mouth is known to be performing both the tasks of chemical digestion and mechanical digestion.
The food is ingested through mouth and the teeth perform the process of mechanical digestion by breaking down the food particles into smaller particles.
Then the saliva gets mixed into the food and the enzymes(amylase) present in the saliva helps in the digestion of carbohydrates.
So, mouth is the organ that performs the process of both mechanical and chemical digestion.
Glucose is quickly broken down by liver and muscle cells to provide energy, which demonstrates that its type of chemical bonds is related to its function.
Gases are natural and in the ground, metals are also in the ground as are non metals -just look at dirt- and minerals are usually found in geodes, which are usually fallen bits of asteroid and meteorite that has survived earth's atmosphere
