Oxygen is a produced as a product of photosynthesis, and later used by both animals and plants for cellular respiration.
A gas tank
Yes. The sun makes plants have photosynthesis and grow, then those plants give off oxegyn while taking in carbon dioxide.
No, our atmosphere is composed mainly of nitrogen (78%). Oxygen comprises around 21% of the atmosphere. Water vapor makes up 1.247% of the atmosphere, the rest being made up of Argon, Carbon dioxide, and trace gases. (The Carbon dioxide protects us from being fried by certain particles flowing from the Sun)
The only deaths in space were the three crew of Soyuz 11 on June 30 1971, who died when their cabin depressurized at an altitude of 168km. The official definition of the beginning of space is 100km, so they just qualify. All the other space-related deaths have been on the ground, during launch, or re-entry below 100km. 3, all members of the crew of Soyuz 11. One more died on landing (Soyuz 1). 14 US astronauts have died in spacecraft in flight (Challenger and Columbia), although all were within the atmosphere, and therefore did not die in space.
Lungs.
Mars does have oxegyn actually, although it's really little because of the interaction between the CO2 in it's atmospere interacting with the sun. Btw people, please stop saying Mars has no oxegyn!
oxegyn in the air

No, there are no gases on the moon as there is no atmosphere.
Yes.

Maybe but if it does it will be in very tiny amounts
