Process by which molecules move fom on area to a higher concentration tona lower?

The process by which molecules move from an area of higher concentration to an area of lower concentration is called diffusion. This movement occurs due to the random motion of molecules, resulting in a net flow from regions of higher concentration to regions of lower concentration until equilibrium is reached. Diffusion is a passive process, meaning it does not require energy input. It plays a crucial role in various biological and chemical processes, such as nutrient uptake and gas exchange.
