Neither of these require energy. Diffusion occurs naturally when a higher concentration of a substance exists on one side of a membrane than the other; molecules will enter into the area of lesser concentration until there is an equilibrium on both sides.
Active transport requires the energy of the cell.
Facilitated diffusion needs some sort of help. Often it would be a protein. Simple diffusion doesn't. If you spill something smelly on the floor in the kitchen, you will smell it all through the house. It will spread by simple diffusion.
Glucose molecules entering a cell typically occurs through facilitated diffusion, which is a type of passive transport. This process involves the movement of glucose across the cell membrane with the help of specific transporter proteins.
diffusion is the simplest type of transport
Yes, passive transport takes place without the use of energy (ATP). This transport is made possible because the movement that occurs due to concentration or pressure differences. These passive processes are called diffusion and filtration. Diffusion (simple and faciliated diffusion and osmosis) occurs because of a concentration gradient and filtration occurs because of differences in pressure.
Facilitated diffusion is passive transport as no energy is used, and a protein channel is all that's required. After that it is simple diffusion down a concentration gradient. Anything with the word diffusion in it is passive transport. Diffusion is just the principle of passive transport.
Facilitated and simple diffusion both transport solutes along a concentration gradient and neither processes require any ATP expenditure.

Active transport is needed to move molecules from an area of low concentration to an area of higher concentration against their concentration gradient. ATP is used as the power source.
Facilitated diffusion does not require energy because it relies on the use of carrier proteins to transport molecules across a cell membrane down their concentration gradient. These carrier proteins facilitate the movement of specific molecules such as glucose or ions without the need for ATP or energy input.
