Question

Why is diffusion insufficient to meet the oxygen requirement of multicellular organisms like humans brainly?

Answer 1

⊕ANSWER⊕

• Diffusion, being a slow process will take a lot of time to circulate oxygen to all the body cells.

• Hence, diffusion is insufficient to meet the oxygen requirements of multicellular organisms like humans.

Answer 2

In multicellular organisms like humans, all the body cells are not in direct contact with the surrounding environment . Thus , every cell of the body will not get oxygen as by the process of diffusion from the environment .

Therefore diffusion is insufficient to meet

the oxygen requirements of multicellular

organisms .
