The way to improve oxygen in the air is by increasing life that give off oxygen as a byproduct such as plant life. Animals use oxygen and give off carbon-dioxide which is used by plants which in turn releases oxygen in the air.
Plants provide a thing called oxygen,which happens to be what we breath.So it gets rid of carbon dioxide and replaces it with oxygen.
Yes, they can. They do produce oxygen and take up carbon dioxide.
Plants need oxygen so they will not grow if there is no oxygen. So if we travel to Mars or the moon, we will have to have to bring oxygen for our greenhouses. Plants improve air quality so we need plants when we visit other worlds.
Plants and trees take in carbon dioxide and release oxygen and so help clean the air.
Oxygen is in the air.
An anaerobe is an organism that grows without air. The organism can only live in oxygen-free conditions. If oxygen is present, the organism could die.
No, there is 21% oxygen in air.
in our air is there mostly oxygen
No. Oxygen is an element that typically comes in the form of O2. Air is a mixture of gasses and Oxygen is just one of them. Air is about 21% oxygen and 78% nitrogen with another 1% being a variety of other gasses.
When photosynthiesis occures...it releases oxygen into the air
There is 21% of oxygen in the air.
Dyr air is about 21% oxygen.
