Water, and your body. :)
Active transport is the process by which a cell uses energy to move molecules or ions across a cell membrane against their concentration gradient. This process requires the use of ATP energy to pump substances from an area of low concentration to an area of high concentration.
Passive transport processes like diffusion and facilitated diffusion move materials across the cell membrane without requiring energy. Diffusion occurs when molecules move from areas of high concentration to low concentration, while facilitated diffusion involves the help of protein channels to facilitate the movement of specific molecules.

Passive transport is the movement of substances across a cell membrane without the use of energy. This process includes simple diffusion, facilitated diffusion, and osmosis. These mechanisms rely on the concentration gradient to drive the movement of molecules.
