passive diffusion requires absolutely nothing, no energy either, the particles simply flow from a high concentration gradient to a low concentration gradient. Active transport however require carrier proteins to allow the particles through the cell membrane
Active transport requires ATP and passive transport does not. Active transport goes against the concentration gradient and passive transport goes with the concentration gradient and includes osmosis, diffusion and facilitated diffusion.

Passive (diffusion).
What is the difference between active attacks passive attacks in GSM network?
Active transport requires energy (ATP, GTP, etc) to work against the electrochemical gradient. Passive transport works with the electrochemical gradient and does not require energy. (Think diffusion)
Diffusion and osmosis are passive and do not require energy.
Active transport requires energy; passive transport does not.

Passive.
No. Facilitated diffusion is a type of passive transport.
Diffusion is passive, it happens everywhere whether living things are involved or not. It results from the natural thermal motion of particles.
