oxygen was created by trees.Trees were created from bacteria and living organisms.Trees create oxygen that we need to survive.
Earth's oxygen atmosphere was primarily created by early photosynthetic organisms, such as cyanobacteria, which converted carbon dioxide into oxygen as a byproduct of photosynthesis. Over millions of years, these organisms accumulated oxygen in the atmosphere, resulting in the oxygen-rich environment we have today.
Stromatolites, which are layered structures created by cyanobacteria, were some of the earliest photosynthesizers on Earth. Through photosynthesis, these cyanobacteria released oxygen as a byproduct into the atmosphere, contributing significantly to the buildup of oxygen over time. This increase in atmospheric oxygen was essential for the development of complex multicellular life forms on Earth.
No, oxygen-17 and oxygen-18 are different isotopes of oxygen. They differ in the number of neutrons each atom contains. Oxygen-17 has 8 protons and 9 neutrons while oxygen-18 has 8 protons and 10 neutrons.
An oxygen free environment may be described as "anoxic" (without oxygen) however the composition of gases in the remaining gases may better describe it:A gas composed of noble gases like argon is called inertA gas which would unite with oxygen or other oxidants is a reducing atmosphereAn atmosphere similar to the Earth;s atmosphere but without oxygen is anaerobic
4 liters of oxygen is 100% oxygen because the volume is entirely filled with oxygen.
