Free oxygen refers to oxygen that is not combined with other elements. It is a diatomic molecule with the chemical formula O2 and is essential for respiration in many organisms. Free oxygen is found in the Earth's atmosphere, where it makes up about 21% of the air we breathe.
free oxygen is basically an oxygen-free-radical oxygen breaks into free oxygen under the action of sunlight (ultraviolet rays) these free oxygen are highly reactive and combine with oxygen molecule to give ozone and ozone helps filter the harmful effects of ultraviolet rays also the ozone layer is the basic reason for human survival on earth as the sun is too damaging, that i would have burnt us alive into tandoori human!!!! LOL
Free oxygen
cyanobacteria
Uranus does not have oxygen in the same form as Earth's atmosphere. Uranus' atmosphere is mostly composed of hydrogen and helium, with small amounts of methane. There is no free oxygen available for breathing on Uranus.
There's not much oxygen on any planet except Earth. I mean "free" oxygen, not chemically combined with other elements. Obviously carbon dioxide contains oxygen combined with carbon, for example.

no
"Free oxygen" refers to oxygen that is not bound to other elements or molecules. It typically refers to molecular oxygen (O2) that is available in the atmosphere for respiration by living organisms.

Oxygen is a pure substance. In nature, free oxygen exists as a molecule of two oxygen atoms covalently bonded, O2.
The free oxygen in Earth's atmosphere primarily comes from the process of photosynthesis carried out by plants, algae, and certain bacteria. During photosynthesis, these organisms use energy from sunlight to convert carbon dioxide and water into oxygen and glucose.Approximately half of Earth's oxygen is produced by marine plants, specifically phytoplankton.
Oxygen is not mined on the planet Earth. It is a free gas in the air. Various minerals ARE mined that contain oxygen.
Nasal cannula cannot reliably deliver free flow oxygen because it relies on the patient's inhalation to draw in the oxygen. If the patient is not breathing or has shallow breathing, the oxygen delivery may be compromised.
