why is diffussion is insufficient to meet the oxygen requirements of multicellular organism like humam
Answers
Explanation:
Diffusion is insufficient to meet the oxygen requirement of multicellular organisms like human because all the cells are not direct contact in environment and diffusion is a slow process. Diffusion is too slow to cover the distance between the gas exchange surface and the sites where the oxygen is required.

Answer:
Unicellular organisms are completely surrounded by the environment, so they can take the required nutrients and oxygen through diffusion process, but multicellular are not completely in touch with the environment and the body cannot be dependent upon the diffusion as they gave complex body structure and they have separate organs for separate functions, so they cannot meet the oxygen requirements through diffusion.
