Diffusion is the net movement of anything generally from a region of higher concentration to a region of lower concentration. In biology, this typically refers to the movement of molecules across a cell membrane. For example, oxygen molecules move from an area of high concentration (outside the lungs) to an area of low concentration (inside the blood) through diffusion. This process does not require energy.
