Diffusion is an example of passive transport because an organism need not expend energy to accomplish diffusion. In diffusion, molecules simply cross a membrane from an area of higher concentration to an area of lower concentration.

Answer

Because it does not require the input of any energy for it to take place. Diffusion is just the movement of particles from a region of higher concentration to a region of lower concentration, something they tend to do on their own.

Active transport is like a person climbing a wall passive is another person going through the open door see?!?
