Osmosis is the spontaneous movement of solvent molecules through a partially permeable membrane. Simple diffusion is the thermal motion of all particles at temperatures above absolute zero. Facilitated diffusion is the process of spontaneous passive transport of molecules or ions.
Diffusion is a type of passive transport where molecules move from an area of higher concentration to an area of lower concentration without the use of energy.
Active transport requires energy; passive transport does not.
Passive transport never requires energy - hence the name passive. Active transport requires the input of energy. Two types of active transport are; primary (using pumps) and secondary (using anti or symports).

Diffusion is a type of passive transport where molecules move from an area of higher concentration to an area of lower concentration without the use of energy.
Passive transport does not require energy, as it involves the movement of molecules across a cell membrane without the input of energy. This includes processes such as diffusion, osmosis, and facilitated diffusion.
Passive transport is called passive because it doesn't require chemical energy intervention to occur. The four main types of passive transport are diffusion, facilitated diffusion, osmosis, and filtration.
Active transport requires energy; passive transport does not.
