Humans and animals use oxygen to breathe. Plants exhale oxygen.
we get oxygen from plants trees,bushes things that have leaves and are big
Oxygen is used and CO2 is produced
We can't do it at all humans can not make oxygen!!!!!!!!!!
The oxygen that plants make is taken up by humans. The humans take the oxygen and transform it into carbon dioxide. When the humans do this then the plants take it and change it back into oxygen. This is a never-ending cycle, without plants, humans and animals would die out, without humans and animals, plants would die out.

Oxygen is needed for the chemical reaction which provides humans and animals with the energy that we need to make our biochemistry work.
humans have changed the world by polluting it and cutting down the trees that make oxygen
Photosynthesis is important for humans because it provides oxygen for us.
Yes, humans inhale oxygen through their lungs. Oxygen is necessary for cellular respiration, where it is used in the process of generating energy for the body's functions.
