no because it is a form of passive transport. only active transport requires energy. facilitated diffusion just means that it cant be just absorbed through the membrane, it must go through specific chanels or be helped by transport proteins. but because facilitated diffusion moves from higher to lower concentrations, it requires no energy.
The movement of a substance through a cell membrane against its concentration gradient is called active transport. Primary active transport requires energy, usually in the form of ATP. Secondary active transport makes use of another substance moving down its concentration gradient to pump a substance against its concentration gradient.
Facilitated diffusion across a biological membrane requires TRANSPORT PROTEINS and moves a substance DOWN its concentration gradient.
Facilitated diffusion across a biological membrane requires energy. Passive diffusion across a cellular membrane does not require any energy from the cell.
It is active transportation. It requires energy of ATP

active transport
Diffusion is the movement of water from a higher concentration of water to a lower. Osmosis is a special form which requires a cell membrane.
Partially permeable membrane(visking tubing) and water
Active transport moves solutes against their concentration gradient; facilitated diffusion moves substances down their concentration gradient.
it is called osmosis and it is the net movement of water particles across a semi-permable membrane against the concentration gradient!
the concentration gradient will help to bring stuff into the cell and to move stuff out. Osmosis likes to move with the concentration gradient. Moving with a concentration gradient is passive transport and moving against it is active transport
active transport
Active transport is a process that removes substances from a cell against the concentration gradient. The molecules move from low concentration to high concentration during this process.
As long as there is a concentration gradient. This is because diffusion occurs which is the net movement of substances from a region of high concentration to a region of low concentration.
In diffusion, the movement of particles across a membrane is driven by an electrochemical gradient-the ion's concentration gradient and the membrane potential. Substances will passively diffuse down their concentration gradient to where they are less concentrated. Since the inside of a cell is negative compared to its outside, the membrane potential will drive the passive transport of cations into the cell and anions out of the cell due to electrostatic attractions.
Diffusion is the movement of water from a higher concentration of water to a lower. Osmosis is a special form which requires a cell membrane.
eflux
the movement of one of the transported substances down its concentration gradient
Partially permeable membrane(visking tubing) and water
The movement of water through a selectively permeable membrane is called diffusion. Water will always diffuse down a concentration gradient, from high solute concentration to low solute concentration.
ATP.
The answer is is OSMOSIS the spontaneous net movement of water across a membrane from a region of low concentration to a solution with a high concentration, down a solute concentration gradient.
