Respiration (breathing) and combustion (fire). Both processes combine oxygen and some form of fuel to produce carbon dioxide, water, and energy.
Oxygen comes from trees you need oxygen to breath
um, oxygen? The name of the element is the name of... the element. If, i.e., the species you wish to describe is a single atom of neutral oxygen, then it is preferable to call it monatomic oxygen or something for clarity.

Oxygen and water.
Oxygen needs 2 more valence electrons to have a full outer shell. Oxygen has 6 valence electrons, and a full outer shell for oxygen is achieved at 8 valence electrons.

2 things:Cells need blood and oxygen to produce.

they need to make photosynthesise to produce 2 things 1-food for themselves and 2- to produce oxygen (they take in carbon dioxide and give out oxygen )
Cellular respiration sometimes is referred to as aerobic respiration, meaning that it occurs in the presence of oxygen, and is not an anaerobic process. Glycolysis is one of the processes in cellular respiration. In the final steps of glycolysis, two hydrogen atoms are removed from each three-carbon compound by bonding to free-floating oxygen atoms in the cytoplasm to form water.
Oxygen absorbers typically last about 1-2 years before they need to be replaced.
Oxygen is essential for the process of cellular respiration in organisms, where it is used to break down glucose and produce energy in the form of ATP. Oxygen is used in combustion reactions, where it helps fuel burning in various processes such as the burning of fuels for energy production or in industrial processes.
