I mean it's in space. So it can't take in air from the outside.

How does the station maintain an air supply for its inhabitants? Do rockets have to make continual deliveries?

I'm really in the dark here. :/

They have a forest of trees, and every time a muma tree gives birth, the baby tree is torn away before being juiced for oxygen. It is all really very cruel.

(*Its actually electrolysis of water)

I did not know that electrolysis of water produces oxygen. Thanks!

Electrolysis, plus resupply: https://science.nasa.gov/science-news/science-at-nasa/2000/ast13nov_1/

In theory, since the ISS is a closed system (or potentially could be), it would be possible to recycle everything, given only an energy source. And the Sun will do fine for that. After all, the Earth hasn't run out of air yet...

Good point. Forever answering the question of why I got a C in science. :p

(Not my best subject. That honour goes to modern history)

But remains the thorny question ... of the smell. Scott Kelly, NASA astronaut, said a few months ago: "Alternatively, the ISS feels either the antiseptic or the garbage bag". Because the air is only recycled in closed circuit

As someone who spend a lot of time on a boat (when I want to get away from idiots surrounding me) i can say that water production on the ocean is also possible, we even reuse the water from A/C.
I did an experiment some years ago, and had a very small greenhouse growing tomatoes and lemons, and they actually grew just fine. Not a big yield but it was ok as an experiment.
