Please help will mark brainlest Which of these statements best describes a similarity between respiration and diffusion?

Both absorb carbon from the atmosphere.
Both release carbon into the atmosphere.
Both increase the level of carbon in the biosphere.
Both increase the level of carbon in the geosphere.

Explanation:

Diffusion is the process whereby gases move from an area of high pressure to low pressure. This includes- Internal respiration - this is the movement in the internal tissues between cells and capillaries, and - External respiration - when gas is exchanged between the alveoli and lung capillaries. Perfusion refers to the blood flow to tissues and organs. Alveoli are perfused by capillaries so the diffusion of oxygen and carbon dioxide can take place.
