Oxygen, of course.
fish need air because they won't be able to breath if they didn't have air, and fish need air badly because they spend most time in the water. fish need air as much as we do.
No,it would need less gravity, not air. It might make the air look soild or gasy but able to be seen
its not so much the air that you need. but you do need something that is in it. oxygen is like a food for cells. the blood carys the oxygen around the body. there is also carbon dioxide (C02) in air. and that's what you breath out.but not everything, but most things.
we need the weather so that we can get air and so it is safe for us

WE BREATHE the air. If we pollute it, we need air, so we breathe it in and get sick.

Squirrels need oxygen, just as humans do, so they breathe in air much the same way as humans do. Squirrel blood cells need oxygen to operate their muscels, bones, and anything else in their body, much the same need for oxygen in humans.
For a 60ft air seeder, you'd need a 4wd tractor that has over 250HP to pull an air seeder
