Role of diffusion in nutrition
Answers
Answer:
Diffusion is important to organisms because it is the process by which useful molecules enter the body cells and waste products are removed. Digested food molecules (amino acids, glucose) move down a concentration gradient from the intestine to the blood.

Answer:
Diffusion is the net movement of anything (for example, atom, ions, molecules) from a region of higher concentration to a region of lower concentration. Diffusion is driven by a gradient in concentration.
The word diffusion derives from the Latin word, diffundere, which means "to spread out."
Explanation:
Some particles are dissolved in a glass of water. At first, the particles are all near one top corner of the glass. If the particles randomly move around ("diffuse") in the water, they eventually become distributed randomly and uniformly from an area of high concentration to an area of low concentration, and organized (diffusion continues, but with no net flux).
