All aerobic living things needs oxygen. Anaerobic organisms do nor need oxygen and may be poisoned by it, facilitative organisms can adjust their metabolism to act as either aerobes or anaerobes.
Plankton
For all animals: oxygen.
Oxygen is needed for respiration. This is how all our cells release energy. All the body cells and white blood cells therefore need oxygen. Red blood cells don't use oxygen, they undergo anaerobic respiration, but they transport the oxygen needed by other cells.
needed by most organisms in the process of
Organisms that require oxygen depend on the oxygen in the air, which was put there by plants.
Oxygen is needed by all organisms for respiration , carbon dioxide is needed by plants for photosynthesis , nitrogen is needed i form of nitrates by plants .
No, Carbon Dioxide is not needed for all organisms because humans and most other animals consume oxygen not carbon dioxide. However plants use carbon dioxide during photosynthesis to create oxygen as a waste product. By the way you really need to check your spelling.
If the world did not have plants then no living organisms would be able to survive. This is because plants produce oxygen that is needed for organisms.
All organisms need oxygen to live.
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.

creates oxygen
All living organisms need water to survive, because they have cells. With air, not all living organisms need air. Some forms of bacteria do not need oxygen to live, and others can't stand oxygen.
