What gas is produced by the cells?

Cells can produce a variety of gases depending on what kind of cells they are and from what organism; most commonly cells can produce Carbon Dioxide, Oxygen or Nitric Oxide.


What is the place with the most oxygen on earth?

The place with the highest oxygen levels on Earth is typically at sea level, where the atmosphere is thickest. Rainforests and other dense vegetation areas also produce high levels of oxygen due to photosynthesis.


What other organisms make air?

No organisms make "air." Air is the natural atmosphere of the earth. Most of it is nitrogen. Most plants take in carbon-dioxide, and produce oxygen. Most animals take in oxygen, and produce carbon dioxide.


Where does most of the oxygen come from?

Most of the oxygen on Earth comes from photosynthesis, a process carried out by plants, algae, and cyanobacteria. These organisms take in carbon dioxide and water and use sunlight to produce oxygen as a byproduct.


Why are phytoplankton critical to life earth?

They produce much of the oxygen in the earth's atmosphere that aerobic life requires, and they are at the base of the food chain in most marine environments


Is oxygen a living organism?

No, Oxygen is a gas and an element. It has 8 protons and electrons. Even though it isn't a living organism, it is necessary for most life on earth (a few microbes breath sulfur instead). No, it is an element with 8 protons and neutrons, and it is required for most things on earth to be able to survive. A few bacteria do breath sulfur instead of oxygen. No. Its just a type of gas on the periodic table of elements,the symbol is O.


What is a aerobic heterotroph?

An aerobic heterotroph is an organism that obtains energy by breaking down organic compounds in the presence of oxygen. These organisms rely on consuming organic molecules from their environment to sustain themselves and carry out cellular respiration to produce ATP for energy. Examples include most animals, fungi, and some bacteria.


What is the most source of oxygen for the earth atmosphere?

The most significant source of oxygen in Earth's atmosphere is photosynthesis by plants, algae, and cyanobacteria. These organisms take in carbon dioxide and water, using sunlight to produce oxygen as a byproduct. This process has been crucial in maintaining the balance of oxygen and carbon dioxide in our atmosphere for billions of years.
