Requires no energy from the cell is the best phrase describes the process of facilitated diffusion.

Any substance that moves systematically from one location of higher concentration to another is said to be diffusing. It may occur inside a cell or in the space between them. Diffusion only occurs in liquids and gases because of the random movement of their particles. It is a crucial process for all living things since it governs the entry and exit of chemicals from cells. Since it occurs spontaneously, there is no need for energy.

The particles run into their container or each other in collision. They veer in a new path as a result. Eventually, the particles cover the entire container. There is no stirring, shaking, or wafting involved in diffusion; it occurs naturally.

Down the concentration refers to the migration of particles from a higher to a lower concentration caused by diffusion.
