Facilitated diffusion requires energy. This is because facilitated diffusion is the transfer of molecules from a lower concentration to a higher concentration.membrain pouch
Diffusion is a passive process that does not require energy. Under experimental conditions it can be observed that both living and dead cells exhibit diffusion.
Simple diffusion
A difference in the concentration throughout space because diffusion doesn't just happen in a cell or aqueous solution by definition diffusion is just from high to low concentration
Down the concentration gradient
Osmosis is when a solvent moves from a lower concentration to a higher concentration. Facilitated diffusion is when a solvent moves down the concentration gradient through carrier molecules.

Active transport moves solutes against their concentration gradient; facilitated diffusion moves substances down their concentration gradient.
Carrier proteins is important in facilitated diffusion. Facilitated diffusion transports molecules from one area of higher concentration on one side of the membrane to an area of lower concentration on the other side .Because the molecules are moving down their concentration gradient , facilitated diffusion is passive transport.
It is because during active transport, the molecules are being transported against and toward the concentration gradient whereas in diffusion, the molecules go from the concentration gradient.

Simple diffusion
Simple diffusion = flow of small molecules ALONG the concentration gradient, does NOT require energy. facilitated diffusion = flow of molecules ALONG the concentration gradient with help of CARRIER PROTIENS or CHANNELS, does NOT require energy active transport= flow of larger or charged molecules AGAINST their concentration gradient, REQUIRES input of ENERGY in the form of ATP.)
Active transport requires more energy than diffusion this is because during active transport, the molecules are being transported against and toward the concentration gradient whereas in diffusion, the molecules go from the concentration gradient.
The random movement of molecules and ions down their concentration gradient (meaning from an area of high concentration to an area of low concentration) is called simple diffusion. Simple diffusion is related to the magnitude of driving force, permeability of the membrane, and surface area.
