From the above diagram, the three (3) different processes that are occurring are:
1. Process A: Diffusion.
- Diffusion refers to the movement of gas molecules from a region of high concentration (top) to a region of lower concentration (bottom) until an equilibrium is attained or reached.
2. Process B: Facilitated diffusion.
- Facilitated diffusion refers to the movement of substances or gas molecules across a cell membrane from a region of high concentration (top) to a region of lower concentration (bottom), especially through the help of transport protein.
3. Process C: Active transport.
- Active transport involves the movement of substances across the cell membrane from a region of lower concentration to a region of higher concentration, against a concentration gradient and in the presence of oxygen.
