A ventilation system is needed in order to obtain oxygen for living organisms and to get rid of carbon dioxide. Surface diffusion utilized by many smaller organisms is not sufficient in supplying the oxygen needs of the body. It is also needed to maintain a concentration gradient in the alveoli.
carbon dioxide or oxygen
yes
Complex multi cellular organisms need a nervous system to be able to contact the brain and be informed on which tasks need performing. Hope this helps...
no it cant because multicellular organisms need specilized cells in order for them to remain stable to focus in one job
A cat is multicellular. Multicellular organisms have more than two cells. A multicellular organism is one that can be seen without the need of a microscope.

because multicellular organisms cannot survive on diffusion alone. as a result, they need these mechanisms to transport nutrients and substances through the body

Cell specialization is necessary to support multicellular life because multicellular organisms need different tissues. This means it needs cells to make up those tissues and perform different functions.
Most multicellular organisms reproduce sexually .
The first multicellular life does not need oxygen. That is the only type of life that does not need any oxygen at all basically. It is because a lot of organisms do not need the respiratory system at all.
