Its ALL from plants.
Oxygen is primarily supplied to the atmosphere through photosynthesis by plants, algae, and cyanobacteria. These organisms convert carbon dioxide into oxygen during the process of photosynthesis. Additionally, a small amount of oxygen is also released through chemical reactions, such as the breakdown of ozone in the stratosphere.
The Earth's atmosphere is composed of about 21% oxygen. This level is important for supporting life on our planet.
Not necessarily. The presence of oxygen in Earth's atmosphere is the result of biological processes that have occurred over billions of years, not simply a function of the biosphere's age. Other factors such as the balance of oxygen-producing and oxygen-consuming organisms also play a role in determining atmospheric oxygen levels.
The most abundant element in Earth's crust is oxygen, making up about 46.6% of the crust by weight.
Oxygen makes up about 21% of Earth's lower atmosphere by volume.
Oxygen can be supplied to a client through an oxygen concentrator, compressed gas cylinders, or liquid oxygen systems.
gurl they aint no oxygen in they atmposphere
The reactants in a fuel cell are typically hydrogen and oxygen. The hydrogen is usually supplied as a fuel source to the anode, while oxygen is supplied to the cathode.
The gas that the body must be supplied with to function is oxygen. Oxygen is required for cellular respiration in the body, where it is used to generate energy from nutrients.
is it oxygen
The earths atmosphere is made up of 78% nitrogen and 21% oxygen
