Question

why is diffusion insufficient to meet the oxygen requirements of multicellular organism like humans​

Answer 1

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 the cells..

Answer 2

heya, buddy !!

:$\implies$ Our body is very huge and complex, each and every cell of the body requires oxygen.And the

process of diffusion is very slow, will take so much time to reach each and every cell. Hence,

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