It's often used to transport nutrients across the epithelium of the gut. It's also used to reabsorb nutrients from filtrate in the kidney. Any time the body needs to move substances against their concentration gradient without wasting excess ATP, you might expect cells to use facilitated diffusion. Facilitated diffusion usually requires less ATP per molecule moved than does active transport.

In the facilitated diffusion the transport protein is needed as well in the active transport.
transport proteins both are carrier proteins and channel proteins
I do believe that the answer is facilated diffusion.
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.
The process the cell must use to allow the protein to enter is rather simple and uncomplicated. The cell uses the process of osmosis and diffusion along a concentration gradient to allow for passage in and out of the cell.

Active transport/Facilitated Diffusion where energy is used
It's often used to transport nutrients across the epithelium of the gut. It's also used to reabsorb nutrients from filtrate in the kidney.

Facilitated diffusion usually requires less ATP per molecule moved than does active transport.
Facilitated diffusion (or facilitated transport) is a form of passive transport that is facilitated by transport proteins. Most often it is used to transport polarized molecules (such as glucose and amino acids) across the cell membrane.

Facilitated diffusion because carrier proteins are being used.

Facilitated diffusion uses proteins to move a molecule across the cell membrane without energy.
