The mechanical processes include chewing (mastication), which breaks down food into smaller pieces, and peristalsis, the movement of food through the digestive tract. Chemically, enzymes in saliva, stomach acid, and pancreatic juices break down carbohydrates, proteins, and fats into soluble nutrients. For instance, amylase in saliva starts carbohydrate digestion, while pepsin in the stomach digests proteins. These processes ultimately transform insoluble food into absorbable nutrients in the intestines.
all the mechanical and chemical that breaks down rock
The breakdown of rock occurs through chemical and mechanical weathering processes. Mechanical weathering involves physical forces, such as freeze-thaw cycles, abrasion, and pressure release, which fragment rocks without altering their chemical composition. In contrast, chemical weathering involves chemical reactions that change the minerals within the rock, such as oxidation, hydrolysis, and carbonation, leading to the dissolution of certain components. Together, these processes contribute to soil formation and landscape evolution.
mechanical wearthering
Yes, Earth's material systems can be affected by both mechanical and chemical reactions. Mechanical reactions can involve processes like erosion, sedimentation, and tectonic activity, which reshape the Earth's crust. Chemical reactions, such as weathering, can alter minerals and rocks through processes like oxidation and hydrolysis. These interactions constantly modify the Earth's materials and their properties over time.
Coal is a chemical compound which contains chemical energy. To convert coal into mechanical energy, you use it (burn it) to produce heat and use the heat to boil water, the steam from which will drive a steam engine which delivers mechanical energy.
Food is broken down into nutrients by the digestive system. Ingested food is transformed into usable nutrients by mechanical and chemical processes in the digestive system.

mechanical , chemical and organic
Yes, mechanical breakdown increases the surface area available for chemical reactions to occur on and therefore the speed of the chemical processes.
Mechanical erosion involves physical processes like abrasion by wind, water, or ice that break down rocks into smaller pieces. Chemical erosion includes processes like acid rain or the action of chemicals that dissolve or alter the composition of rocks over time. Both mechanical and chemical processes contribute to the overall weathering of rocks.
Hydrolysis is one chemical process that accomplishes chemical digestion. There are other chemical and mechanical digestive processes.
I don't think so, mechanical change is when you use something to change the appearance of the object (your Jaw and food for example). Physical change can be caused bye a chemical substance and by and object ( mechanical change ) You welcome :)
No chemical or mechanical digestion occurs in the esophagus, only propulsion, which is one of the six digestive processes.

Mechanical energy can change into chemical energy through processes like photosynthesis in plants. In this process, light energy is converted into chemical energy stored in the bonds of molecules like glucose.
Nuclear energy vastly overshadows the energy from chemical and mechanical energy, because nuclear energy is based on the release of binding energy, which lies at the core of everything. It is the Strong Atomic Force.
