Practically all foods contain oxygen; and the first is of course water. Also the Earth atmosphere contain approx. 20 % oxygen as a gas.
It is most likely oxygen, as plants produce oxygen through the process of photosynthesis. Oxygen is a byproduct of the reaction that occurs when plants convert carbon dioxide and sunlight into energy.
The color code for an oxygen cylinder is typically green. This color helps to easily identify and differentiate oxygen cylinders from other types of gas cylinders.

Oxygen
Oxygen has a lower first ionization energy compared to nitrogen and fluorine because oxygen has a larger atomic size and a weaker effective nuclear charge, making it easier to remove an electron from an oxygen atom.
The number 8 above the element symbol O on the periodic table represents its atomic number, which indicates the number of protons in an oxygen atom's nucleus. This helps identify the element as oxygen specifically among the other elements.
Oxygen gas can be identified by its physical properties, such as its colorless and odorless appearance. It can also be tested by its ability to support combustion, as oxygen is necessary for fire to burn. Chemical tests, such as reacting oxygen gas with a fuel to form water and carbon dioxide, can also be used for identification.
