Oxygen is needed for the chemical reaction which provides humans and animals with the energy that we need to make our biochemistry work.
Oxygen is essential for respiration, i.e. breathing.
Photosynthesis is important for humans because it provides oxygen for us.
No i believe they do not cause humans get oxygen from trees animals really are not different from humans so animals get the oxygen from trees just like humans
Oxygen is the gas humans and animals need to breathe in.
Soil gives nutrients to plants-plants make oxygen-humans hog up along with all other animals all the oxygen. that is why its important.
Humans and animals use oxygen to breathe. Plants exhale oxygen.
What do you think will happen to animals and humans if the amount of oxygen in the air is reduced?
Oxygen is important to the society because without it, we could not live. we need Oxygen for us humans to live, for the animals and environment. that is the most important point as to why we need Oxygen. we also use Oxygen for hospitals, burning things like paper, and more. Oxygen is something we have to live with as it is what we survive on.
Plants supply food and oxygen for animals and humans.
Humans and animals breathe in oxygen and breathe out carbindioxide. The trees breathes in the carbindioxide and breathes out the oxygen. So a tree living in any ecosystem is important because without it anything in the area wouldn't be able to breathe.
Plants use photosynthesis to make oxygen and glucose. Without plants, all animals including humans would die from no food and no oxygen to breathe.
The most important aspect of air is that it keeps humans and animals alive. The air contains the oxygen that we need to breathe.
Humans ARE animals. All animals breath oxygen, so all animals would be in trouble in space (unprotected).
