Phagocytosis is the cellular process where a cell consumes a food particle that is too large to pass through a protein channel. It then forms an internal phagosome, or "food vacuole".

protein binds to a particle and uses energy to move through the cell membrane
Facilitated diffusion occurs through a protein channel by allowing specific molecules to pass through the cell membrane with the help of a protein channel. The protein channel acts as a tunnel that facilitates the movement of molecules that are too large or polar to pass through the membrane on their own. The molecules bind to the protein channel, which changes shape to allow them to pass through, ultimately helping them move across the membrane.
A protein that forms an ion channel through a membrane is most likely to be a transmembrane protein. Transmembrane proteins span the lipid bilayer, allowing them to create channels for ions to pass through the membrane. Peripheral proteins are typically found on the surface of the membrane and do not form channels.
It requires energy, and a protein carrier molecule. The large particle binds to the protein carrier on the inside of the cell. It is then transported across the membrane as a result of a conformational change in the protein (think of it flipping), and then it is released on the outside of the cell. Again, this requires some source of energy.
