It is frozen (compressed) into a liquid state- it's contained using fractional distillation of liquid air
I didn't know oxygen came from a state. Did it originate in Oregon or Mississippi?
Animals obtain oxygen from air by breathing air into their lungs where it is attached to hemoglobin molecules in a chemical reaction.
Industrial facilities obtain oxygen from air by cooling the air to very low temperatures so that eventually the oxygen condenses to a liquid and falls out like rain.
In photosynthesis CO2 and H2O are taken up by chlorophyll and broken apart, using sunlight as an energy source, into carbon and oxygen. The carbon is absorbed by the plant as sugar to help it grow, while the oxygen is released.
6CO2 + 6H2O + energy (sunlight) --> C6H12O6 + 6O2
In the equation above, six atoms of carbon dioxide plus six atoms of water yields a single sugar and six diatomic molecules of "free" oxygen.
Most of earth's oxygen is not produced by trees and grass but by cyanobacteria, the "blue green" algae in the oceans.
Oxygen is separated from air in huge industrial air separation plants, the plants compress the air, rapidly decompress it then compress it again, this process is repeated over and over again, this reduces the air temperature so much that it eventually turns to a liquid, in liquid form the different gasses (mostly nitrogen, oxygen and argon) separate out at different temperatures, enabling the plant to draw off the liquid oxygen (known as LOX) into giant insulated 'cryogenic' tanks, LOX is extremely cold (-183c), it can be used in industrial, medical and scientific processes as a liquid or carefully allowed to warm up and returned to a gas, its then stored in compressed gas cylinders and has a huge range of uses.
Hydrolysis can be effected by applying a voltage across water. inverted cylinders over the anode and cathode will collect hydrogen and oxygen gas.
It is removed by fractional distillation if liquified air.
Animals need AIR to breath in - AIR is made up of about 80% Nitrogen and 20% Oxygen. The animals use the Oxygen in the AIR.NOTE if an animal were to breath 100% Oxygen this would eventually kill it, Pure Oxygen is toxic.They need to breath AIR.
air sacs
Dogs obtain oxygen by inhaling it through the air and traveling to their lungs. From their it goes to the bloodstream.
Breathing air through lungs Breathing Oxygen in water via gills Absorbing oxygen through the skin (mainly amphibians)
Oxygen partially dissolves in water. Respiratory systems of aquatic animals are adapted to get this dissolved oxygen. They have gills for respiration.
All mammals obtain their oxygen from the air.
by fractional distillation of liquefied air oxygen is obtained due to it's boiling point
"Oxygen is obtained for industrial use by the fractional distillation of liquid air, by the electrolysis of water, or by heating manganese oxide with potassium chlorate.
Most of the gases in air, Nitrogen, Oxygen, Argon and others are obtained by fractional distillation of liquid air.
It is obtained from air. Oxygen is not is not produced in dark reaction but in light reaction
A mixture is obtained; 80 % N and 20 % O is air.
Cellular respiration releases CO2 into the air.
Oxygen is found as a free molecule in the air and as a component of many organic and inorganic compounds in the earth's crust. For commercial purposes, it is usually obtained by using extreme cold to condense it from the atmosphere.

It is usually obtained as a by-product in the production of oxygen and nitrogen through fractional distillation of air.
Mammals take in oxygen from the air they breathe. High concentrations of oxygen in the lungs replenish the oxygen-poor red blood cells that pass through. The cells then carry the oxygen through the body.
Oxygen is obtained from the atmosphere by a process called Respiration, this involves inhaling air and filling small air sacs in the lung, at which point the oxgen passes into the bloodstream through a process called Diffusion.
