Answer 2

Answer:

hi the answer is in explaination

Explanation:

Multicellular organisms such as humans possess complex body designs. They have  specialised cells and tissues for performing various necessary functions of the body such as intake  of food and oxygen. Unlike unicellular organisms, multicellular cells are not in direct contact with  the outside environment. Therefore, diffusion cannot meet their oxygen requirements.
