The human body breaks down food for absorption and assimilation through the process of digestion. Both mechanical and chemical digestion is used to spread the food pieces through the human body.

Heterotrophs are organisms that uses organic compound as its source of food whereas detritivores are organism that uses organic waste as its source of food.
While both systems communicate to many parts of the body, and control aspects of its functioning, the nervous system acts quickly, and the endocrine system acts more slowly.Both systems use chemical messengers to communicate from cells to other cells in the body. The endocrine system uses chemicals called hormones, and the nervous system uses chemicals called neurotransmitters.The endocrine system releases hormones into the blood stream, which transports them throughout the body where they act on cells anywhere in the body when they reach cells which have the corresponding receptors.The nervous system releases neurotransmitters from a neuron into a very small gap called a synapse where it diffuses very quickly to another neuron.It takes much longer for a hormone to reach its distant target by being moved around the body by the blood stream than it takes neurotransmitters to move between neurons and for a consequently generated action potential impulse to be moved along a neurons axon to its destination.
The process of finely dividing food into various sizes by rubbing it on a grater involves using a kitchen tool called a grater. This tool features sharp-edged holes that shred or slice food items, such as cheese, vegetables, or fruits, into smaller pieces. The size of the holes determines the fineness of the food, allowing for different textures and uses in cooking. This technique is commonly used in preparing ingredients for salads, toppings, or flavoring dishes.

The process of photosynthesis uses sunlight, carbon dioxide from the air, and water to produce food (glucose) for the plant. This process takes place in the chloroplasts of plant cells.
it uses the food as energy around our body
Metabolism is the process by which your body converts food and drink into energy that is used to function properly.
it is called respiration.
When you eat food, your body uses chemical energy from the nutrients in the food to convert it into mechanical energy that powers your muscles and movement. This process involves breaking down the food into smaller molecules through digestion and then using these molecules to generate energy through a series of biochemical reactions in your cells.
Respiratory system
The digestive system is what the body uses to process the food that is taken in through the mouth. It breaks the food down for many areas to use and then gets rid of the waste.
The point of eating food is that the body uses it; any food that you eat will be used in some way.
Photosynthesis
Egestion, the process of removing indigestible waste from the body, typically occurs in the large intestine or rectum. This waste material is formed into feces and is eventually expelled from the body through the anus during a process known as defecation.
