Nutrients are substances that are absorbed by the body through the process of digestion.
Digestion
Digestion is the breakdown of absorbed substances, Respiration, on the other hand, is the breakdown of food molecules with a release of energy.

The process by which food substances are chemically changed into simpler forms that can be absorbed is called digestion. This process involves the breakdown of complex molecules into smaller molecules that can be transported and utilized by the body for energy and nutrition.
Cells can digest substances through intracellular digestion, where enzymes break down molecules inside the cell's cytoplasm, or through extracellular digestion, where enzymes are secreted outside the cell to break down larger substances before they are absorbed.
Synthesis is the process of combining simple substances to form more complex ones, while digestion is the breakdown of complex substances into simpler ones that can be absorbed and used by cells. In synthesis, energy is usually required, whereas in digestion, energy is released as complex molecules are broken down.
In digestion, several substances are diffused, primarily nutrients such as glucose, amino acids, fatty acids, and glycerol. These nutrients are absorbed through the intestinal walls into the bloodstream. Additionally, water and electrolytes are also absorbed via diffusion, helping to maintain fluid balance in the body. This process allows the body to utilize the essential components derived from food.
