osmosis


simple diffusion


active transport


facilitated diffusion

Answer 1

diffusion

Step-by-step explanation:

Answer 2

Simple diffussion

Step-by-step explanation:

It is simple diffussion because it is the movement of gases or molecules of substance from a region of higher concentration to a region of lower concentration without using energy. Through this process gases are exchange between the alveoli of lungs and blood of the circulatory system. Carbon diffuses from tissues to lungs and oxygen diffuses from lungs to Tissues.
