Yes. If anything that can't breathe is something called abiotic or something that is not alive.
No, they cannot. All living things need oxygen to breathe. Sea Monkeys (and all fish) breathe the oxygen that's in the water. By not purifying the water, they will eventually breathe all the air That's in the tank, and then suffocate.
well i know alot but i will just give you the characteristics of living things..... - can reproduce - can grow - can breathe - can live and die that's all i have for now
Nobody knows why, but for some reason all living things need some sort of gas exchange to live, even trees.
One of the living things is trees. Without trees we can not breathe.
All living things need water to live. Whether it is to breathe or to keep them hydrated, life as we understand it cannot exist without water.
Air
Bananas do not breathe, nor live at all. But they produce carbon dioxide and ethylene gas when they are ripening.
Grow , Breathe and Move
Yes of course they can because they are living things

It is not possible to have no brain. If you do not you will not live a life. If you did not have a brain your body would not know how to move, breathe and do neccesary things to live.
They all breathe air !
