Photosynthesis in plants adds oxygen to the air. That's because the process uses H2O (water). Photolysis (splitting with light) uses sunlight, or whatever source of light is being used by the plant, to split the water into H+ (positively charged hydrogen ions) and O2, oxygen atoms. The plant only needs the hydrogen ions, so the oxygen is released through the stomata of the plant's leaves. It then enters the atmosphere.
Oxygen is the component of air that is used in the process of burning. It reacts with the fuel to produce heat and light.
Oxygen can be obtained from the air by heating it to high temperatures, which causes the oxygen molecules to separate from the nitrogen and other gases in the air. This process is known as fractional distillation or air separation.
People get oxygen through the air they breathe. Oxygen is present in the Earth's atmosphere, comprising about 21% of the air we inhale. Our bodies extract oxygen from the air and use it to generate energy through a process called cellular respiration in our cells.
Your body absorbs some of the oxygen out of air in your lungs
In the first stage of the contact process, air is passed rapidly to ensure a quick reaction with the catalyst. This rapid flow of air helps distribute the oxygen evenly, leading to efficient conversion of oxygen into oxides. If the air passed slowly, only part of the oxygen would react, resulting in wasted resources.
Combustion. The burning of any material.
oxidation

adds oxygen to the air
The process that adds oxygen to ocean water is called oxygenation, which occurs through a variety of natural processes such as photosynthesis by marine plants and phytoplankton, as well as atmospheric exchange. Oxygen can also be added through mixing of surface waters with deeper, oxygen-rich waters through ocean circulation.
Photosynthesis
By using an air stone or a filter that adds oxygen to the water.

plants give off oxygen and so do animals and that's how it gets in the air
The term for a process that does not require oxygen is anaerobic. Anaerobic processes can take place in environments without air or in the absence of oxygen. This type of metabolism typically produces byproducts such as lactic acid or ethanol.
The process that adds gases to the atmosphere is volcanic activity, which releases gases such as carbon dioxide and sulfur dioxide. The process that removes gases from the atmosphere is photosynthesis, where plants absorb carbon dioxide and release oxygen.
In the process of respiration OXYGEN is taken in from the atmoshpere and CO2 is released.
