The process that requires energy among the options provided is the "Active transport of Na+ ions out of a cell."

Here's why:

1. Diffusion of carbon dioxide out of a cell: This is a passive process, meaning it does not require energy. Carbon dioxide, being a small molecule, can easily pass through the cell membrane from an area of high concentration (inside the cell) to an area of low concentration (outside the cell).

2. Osmosis: This is also a passive process. It is the movement of water molecules across a semi-permeable membrane from an area of low solute concentration to an area of high solute concentration. It does not require energy.

3. Facilitated diffusion through a membrane transport protein: This is another passive process. It involves the movement of molecules across the cell membrane via special transport proteins embedded in the membrane. These molecules move from an area of high concentration to an area of low concentration, so no energy is required.

4. Active transport of Na+ ions out of a cell: This is an active process, meaning
