Answer 1

Answer:

$\huge\underline\bold\red{AnsweR...}$

Diffusion is unable to meet the oxygen requirements of multi-cellular organisms such as humans because diffusion is one of the slow processes. That is a lot of time is required for oxygen to circulate to all the cells of the body. ... Therefore, through diffusion, it becomes difficult for oxygen to reach all the cells

Multi-cellular organism’s like humans have very big body and require a lot of oxygen to diffuse into body quickly in order to meet the oxygen requirement. Diffusion is a slow process which will take a lot of time to circulate oxygen to all the body cells. Because of its slow nature diffusion is insufficient to meet the oxygen requirements of multicellular organisms like humans.
