Oxygen is not omnipresent on Earth; it makes up about 21% of the Earth's atmosphere. It is produced through processes like photosynthesis by plants and organisms in the oceans. Without these processes, the levels of oxygen on Earth would gradually decline.
Oxygen makes up about 21% of the Earth's atmosphere.
About 50-80% of the Earth's oxygen comes from algae, with the majority being produced by phytoplankton in the oceans. Algae are vital for oxygen production through photosynthesis, which converts carbon dioxide into oxygen as a byproduct.
Oxygen is a gas that is always present in Earth's atmosphere. It makes up about 21% of the air we breathe and is essential for sustaining life.
Oxygen makes up about 21% of Earth's atmosphere due to its production by photosynthesis in plants and algae. This high concentration of oxygen allows for the respiration and survival of many aerobic organisms on Earth.
The boiling point of oxygen is -183 degrees Celsius. Because it is this low, oxygen will always be a gas at room temperature.

Oxygen
About 2% of the Earth's oxygen it produces.
21% Oxygen, 78% Nitrogen and 1% Other Gases
Oxygen, nitrogen, and various other gases are always present in the air. These gases are essential for supporting life on Earth.
Oxygen makes up about 21% of the Earth's atmosphere.
A star is much bigger than earth.
A small percent . exhaled air always contains oxygen .
The oxidation state of oxygen in alkaline earth metal oxides is -2. Alkaline earth metals always have a +2 oxidation state, which means oxygen has to have a -2 oxidation state to balance the charges in the compound.
