In chemistry:- The movement of particle from higher concentration to lower concentration is Called diffusion for ex-distribution of pefume where it is sprayed in one part of room yet soon you can smell it everywhere and movement of drop of food colour in a glass of water where eventually the entire glass will be coloured
In biology:-diffusion is the spontaneous movement of molecules from region of higher concentration to one of lower concentration ,until uniform concentration is finally achieved.for ex:-a gas such as co2 gets accumulated in higher concentration inside the cell.
