Organisms that require oxygen depend on the oxygen in the air, which was put there by plants.
When plants go through photosynthesis, they release oxygen into the air. Any plant, including greens, that go through photosynthesis produce oxygen. The oxygen that is produced, we use it.
plants need water, air, sunlight and oxygen.
Green plants.
Plants release oxygen as a byproduct of photosynthesis, which is the process they use to convert sunlight into energy. During photosynthesis, plants take in carbon dioxide and water and produce oxygen. This oxygen is then released into the air through tiny openings in the leaves called stomata.
They get the oxygen from the air they breath.
Oxygen rich air enters the body through the lungs.
Oxygen
Plants taken in the air we breath as carbon dioxide and release it back into the air as oxygen.
Yes, there would still be free oxygen in the air if there were no trees. There are many plants that are not trees and that release oxygen. In fact, the Earth's atmosphere was rich in oxygen due to the metabolism of plants in the oceans ages before the first trees appeared on the land.
World wide, including deserts, the oxygen level of the atmosphere is about 20.95% by volume.
No, actually plants are producers of oxygen. They intake carbon dioxide (which we exhale) and then add oxygen to the house's air.
Air is rich in nitrogen, oxygen, and other gases such as argon, carbon dioxide, and water vapor. Oxygen is the most abundant element in the Earth's atmosphere, making up about 21% of the air we breathe.
Plants release oxygen into the air during transpiration.
Trees and plants
The aveoli of the lungs are filled with oxygen when you take a breathe in.
well this is so obvious. if there where no plants then we cant survive because plants give off oxygen or in other words the air we breath. no plants=no life that needs air or oxygen
