Question

What is diffusion insufficent to meet the oxygen requirment multicellular organism like human ?

Answer 1

diffusion Is in sufficient to meet the O2 requirement in multicellular organisms like in humans because the volume of the human body is big and hence the oxygen cannot defuse to each and every single cells of the body very quickly..hence diffusion and osmosis is insufficient to meet the oxygen levels of multicellular organisms. :)
