Question

why is diffusion insufficient to meet the oxygen requirements of large multicellular organisms 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 all the cells....

Hope it help you

Answer 2

Answer:

Diffusion is unable to meet oxygen requirements of multi-cellular organisms like humans because diffusion is a slow process.

EXPLANATION:

This means that the time taken for oxygen to circulate to all body cells is more. In addition, humans need a lot of oxygen in their cells and tissues so that the body activities can take place in the right manner and in time.

With diffusion, oxygen can’t diffuse into all body cells in a quick manner because the human body is large and has a large number of cells and tissues.
