How do organisms live without a circulatory or respiratory system?

You don't need a "system" if you're small enough so that the function can be distributed throughout your entire body - as are all single celled organisms.
But it works all the way up through jelly fish.

What the most important the circulatory and respiratory systems or the digestive system and why?
Well, it depends on the organism an the requirement. If you talk about lower organisms like poriferans they don't have circulatory system, respiratory system neither digestive system, simple diffusion occurs in their body as they do not need such system because of their environment and simplicity of development. If you consider flat worms (platyhelminthes) they have a low digestive system but lack any circulatory system as their cells are enogh close to the environment simple diffusion fulfills the respiratory requirement. The need, importance and significance increases with the complexity of an orgnism. As the man is most complex each system is really important. Without digestive system you can't make food simple,without respiratory system you can't yield energy, without circulatory system you can't supply energy or nutrients to the cells at distances. Hope you've got the answer of the question :)
