no they dont give off oxygen
Oxygen does not have just one use.
No, oxygen does not give you a headache. Headaches can be caused by various factors, but oxygen itself is not one of them.
Eating does not give one oxygen, but oxygen is needed by tissues and organs to convert the food you eat.
Air gives use Oxygen!
No. Animal cells use Oxygen and give off carbon dioxide as a waste product. Plant cells use carbon dioxide and give off oxygen.
Well animals do but plants don't. Plants don't actually really use oxygen- they give it out. They use the sunlight and Carbon Dioxide in photosynthesis and the by-product (what they give out) of this is Oxygen.
I think when they receive carbon dioxide
Plants give out oxygen which we take in and then we give out carbon dioxide which the plants take in
Plants give of oxygen and need to use carbon dioxide and sunlight to make food. This makes them perfect partners to animals since we give off carbon dioxide and need oxygen to make ATP (energy).
it's used to make paper, and maple syrup. also trees give us oxygen and we give carbon dioxide and they use it to make oxygen.
The way to improve oxygen in the air is by increasing life that give off oxygen as a byproduct such as plant life. Animals use oxygen and give off carbon-dioxide which is used by plants which in turn releases oxygen in the air.
