Question

How diffusion is useful in living being?

Answer 1

Answer:

Explanation:

→ Diffusion is important to organismsbecause 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.

→ Diffusion is a transport mechanism (another example of a transport mechanism is advection) in which the material moves from a region of higher concentration to a region of lower concentration. Think of a cube of sugar in a glass of hot water. The sugar moves from the cube (a region of higher concentration) to hot water (a region of low concentration of sugar).
