Detailed explanation-1: -Osmosis, facilitated diffusion and simple diffusion do not require energy.

Detailed explanation-2: -Facilitated diffusion does not require high energy molecules such as ATP. This type of diffusion uses channel proteins and carrier proteins to transport molecules across the plasma membrane. Facilitated diffusion involves the movement of molecules from areas of higher concentration to areas of lower concentration.

Detailed explanation-3: -Osmosis, facilitated diffusion and simple diffusion do not require energy.

Detailed explanation-4: -Diffusion is the net movement of anything (for example, atoms, ions, molecules, energy) generally from a region of higher concentration to a region of lower concentration. No ATP is required in this process.

Detailed explanation-5: -Simple diffusion is the movement of substances from a region of higher concentration to a lower concentration along the concentration gradient without the expenditure of energy. (ATP). Simple diffusion does not require special carrier proteins.
