It's not. Diffusion does not require energy.
Diffusion does not require the use of any ATP.
In cells, passive diffusion is energy independent and therefore does not require ATP. This is opposed to active transport which requires either energy in the form of ATP or a charge gradient to move a molecule or ion across the membrane.
Diffusion and Osmosis.... I think. It would be better to double check ;)
diffusion or osmosis (diffusion of water)
ATP is what energy is stored as in mitochondria in eukaryotic and prokaryotic cells. ADP is what is left when a triphosphate is used for energy in the cell for example facilitated diffusion where ATP (Adenosine Triphosphate) is used and it then becomes ADP (Adenosine Diphosphate).
No, net diffusion is a natural phenomenon that requires no ATP.
The relative concentration of molecule X determines the direction and rate of diffusion; if there is a greater concentration gradient of molecule X, more ATP will be used to facilitate the diffusion process. ATP is used to power certain transport proteins that move molecules against their concentration gradient, so the amount of ATP used is dependent on the concentration gradient of molecule X.
Facilitated diffusion is an inactive mode.So no ATP cost.

No only active transport requires ATP.
Diffusion
yes

Chemiosmosis.
no it is not because it does not require the use of ATP
