What else can I help you with?
Why isn't the oxygen in the earths atmosphere is not used up by the breathing of humans and other animals?
As you breath in oxygen your body exchanges it for carbon dioxide which is the air you breath out. As you and all other oxygen breathing animals do that, the earths plants to the opposite they breath carbon dioxide and release oxygen. That is why it is important to protect the worlds plants. We need each other.
Where the animals get the oxygen they need?
Land animals get the oxygen they need from the atmosphere. Most aquatic organisms get oxygen dissolved in the water in which they live, and others, like alligators and crocodiles, get oxygen from the atmosphere. Most Plants Give Out Oxygen, And Plants Are All Around Us.
Could you survive on Earth without the atmosphere?
No, because the atmosphere keeps in all the oxygen. Without the atmosphere the oxygen would escape.
If all life on Earth were to cease the atmosphere would revert to its primitive oxygen-poor composition and become poisonous to modern plants and animals?
true
What percentage of your atmospheric gases is oxygen?
My atmosphere is the same as your atmosphere since we all live on the same planet. Oxygen makes up about 19.5% of the atmosphere.
Where does most of the atmosphere oxygen come from?
From plant life. Animals including humans exhale carbon dioxide. Carbon dioxide is a heavy gas and fall to the ground. Whereupon it is absorbed by plant life. Under the process of photosynthesis, carbon dioxide in the plant is broken down into carbon and oxygen. The carbon is retained in the plant as biomass, and the oxygen is released back into the atmosphere, for animals to breathe. It is all part of the oxygen/carbon cycle.
What spheres does oxygen cycle through on earth?
Phosphorus cycles through all sphered except the atmosphere
What puts oxygen in the atmosphere?
plants trees and grass all provide oxygen.
Why is the atmosphere classed as an oxygen atmosphere?
Earth's atmosphere is mainly nitrogen, oxygen, carbon dioxide, and water vapor. Oxygen is the most reactive of these. Oxygen allows all of the life as we know it on earth. Even though oxygen is less than 1/4 of the atmosphere it is the most important part.
Is the destruction of rain forests a serious problem?
It will be gone forever once its totally destroyed, and all the animals that live there will die, too. The Rainforests are where a large portion of the oxygen is produced on the planet, and where carbon dioxide is removed from the atmosphere. The loss of these forests is upsetting the ecology of the planet. With no oxygen, animals will all die.
Where do skunks get their oxygen from?
Skunks, like all mammals, get most of their oxygen from the natural atmosphere.
Gas given off by plants that is needed by animals?
The gas given off by plants that is needed by animals is oxygen. Through the process of photosynthesis, plants convert carbon dioxide into oxygen, which animals then breathe in to support their respiration. This exchange of gases between plants and animals is vital for the survival of both organisms.
