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

Answer:
Multicellular organisms such as humans possess complex body designs. They have specialised cells and
tissues for performing various necessary functions of the body such as intake of food and oxygen. Unlike
unicellular organisms, multicellular cells are not in direct contact with the outside environment. Therefore, diffusion
cannot meet their oxygen requirements.
