Low concentration.
The movement of particles from an area of low concentration to high concentration is an active process.
The term for this is diffusion. If they are particles of water, the term is osmosis.Osmosis takes place through a semi-permeable membrane, like that of a skin cell.When thinking of Diffusion it's best to think of spraying aerosol in one corner of the room, eventually the smell will travel, or diffuse to other areas of the room.
if something diffuses e.g. particles through the air or CO2 out of body cells means the particles go from a high concentration to a low concentration
Diffusion is the net movement of particles from an area of high concentration to an area of low concentration.
Diffusion. This process occurs due to the random movement of particles, leading to a net movement from regions of high concentration to low concentration until equilibrium is reached.

I'm pretty sure it's Osmosis.
The movement of particles from an area of low concentration to high concentration is an active process.
Through passive transport
Osmosis is the random movement of particles across (through) a partially permeable membrane along a concentration gradient from an area of high concentration to an area of low concentration. Diffusion is the random movement of particles in a solution from an area of high concentration to low concentration. Eventually the particles will be uniformly and randomly distributed.
Diffusion. This is the process by which particles move from an area of high concentration to an area of low concentration in order to achieve equilibrium.
Diffusion is the movement of particles from an area of high concentration to an area of low concentration. In gases, diffusion occurs rapidly due to the high kinetic energy of the particles. In liquids and solids, diffusion is slower but still occurs as particles move and spread out over time.
Diffusion is the movement of molecules from an area of high concentration to an area of low concentration. Osmosis is the movement of water molecules from high to low through a partially-permeable membrane. This is what makes osmosis different to diffusion.
