By the process of photosynthesis, trees take in the Carbon Dioxide (CO2), water, and sunlight, to make food, and release oxygen as a waste product
Yes, trees do provide most of our oxygen for the atmosphere
Trees and plants provide humans and animals with oxygen, in return we provide them with carbon dioxide.. so aslong as we still have trees and plants, oxygen will continue to be reproduced.
trees and grass...trees provide oxygen and grass provides food for the animals
plants trees and grass all provide oxygen.
You can't. Unless you had some other way to reproduce oxygen. Trees provide us with oxygen by taking in carbon dioxide and putting out oxygen. Trees provide some of our oxygen though the vast majority comes from plant sources other than trees. Mainly marine plants.
Well the trees provide us with oxygen, and we provide them with carbon dioxide. So if you planted more trees, we'd have more oxygen and they'd have more carbon dioxide! :D
Trees provide oxygen without trees this would be just a dead planet!
They provide oxygen for all humans to breathe
From the atmosphere, trees and plants provide oxygen.
they provide oxygen which helps us breathe
Trees provide oxygen, homes for animals, and help retain the soil when it rains.
We won't be able to live as trees provide us with oxygen.
