lysosomes
well, enzymes are proteins that break up food molecules and digestion is when large protein molecules are broken down
mitochondria
Yes, birds rely on a combination of mechanical digestion in the gizzard, aided by grit or stones, and chemical digestion through gastric acids to break down food effectively. The gizzard's muscular contractions help grind up food, while the acids help further break down the food particles.
Respiration I believe.
Somach acid & saliva
A series of chemicals breaks down food. Lysosomes are cellular organelles that break down waste particles and even food particles.
It is very complex process. Food enters in cell in form of simple molecules (for example Glucose). It uses various enzymes and chemicals to break these molecules in to energy and other by products.
Digestive to digest (main part) food, Endocrine to break it down and release chemicals to break it down(if you consider it a system whichh most don't), Circulatory (to transport the broken down molecules), and Excretory to get ride of wastes.
The process you are referring to is called digestion and it occurs in living organisms to break down food into smaller molecules that can be absorbed and used for energy. In cells, a process known as autophagy uses chemicals to break down and recycle worn out cell parts, helping maintain cellular function and health.
You are saliva. Saliva contains digestive enzymes that help break down food into smaller molecules that can be easily absorbed by the body.
When cells break down food through a process called cellular respiration, they release energy in the form of ATP molecules. This energy is then used by the cell for various functions such as growth, repair, and movement. Waste products like carbon dioxide and water are also produced during this process and are typically expelled from the cell.
They break down food molecules which make it easier for the body to digest the food.

lysosomes
To break down the food molecules.
Lysosomes are the organelles that release chemicals to break large food particles into small ones.
