Most but perhaps not all began when tiny organisms known as cyanobacteria, or blue-green algae (in the seas and oceans) began conducting photosynthesis: using sunlight, water and carbon dioxide to produce carbohydrates and oxygen.
In fact, all the plants on Earth incorporate symbiotic cyanobacteria (known as chloroplasts) to do their photosynthesis for them today.
There was no oxygen in the beginning. Plant life developed and released oxygen gas into the atmosphere over a long period of time.If that had never happened, there would not be much if any free oxygen in the atmosphere and aminal life as we know it would never have developed.
When animals exhale, they release a gas called Carbon Dioxide (CO2) which can be lethal to animals if the gas is present in large quantities. Through the process of photosynthesis plants absorb carbon dioxide from the atmosphere and release oxygen as a byproduct. This helps animals because they need oxygen in order to breathe.

Yes, oxygen is a naturally occurring element that is essential for life on Earth. It is a colorless, odorless gas that makes up about 21% of the Earth's atmosphere. Oxygen is also found in compounds such as water and carbon dioxide.
The atmosphere stores gases such as nitrogen, oxygen, carbon dioxide, and water vapor. These gases play a crucial role in regulating Earth's temperature and providing the necessary conditions for life to thrive.
No. Earth's atmosphere most likely originate from volcanic atmosphere. The oxygen is produced by plants.
The most abundant gases are nitrogen and oxygen in the Earth atmosphere.
the layer of the atmosphere that holds oxygen is the troposphere and its pause is tropopause
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.
The second most abundant gas in the Earth's atmosphere is oxygen, which makes up about 21% of the gases in the atmosphere.
Most of the oxygen in Earth's atmosphere comes from photosynthesis carried out by plants, algae, and cyanobacteria. These organisms utilize sunlight to convert carbon dioxide into oxygen during this process.
The oxygen molecule, the form of oxygen found in the Earth's atmosphere, is 100% oxygen. There fore it is the material that has the most oxygen in it.
Nitrogen & Oxygen.
The most of the oxygen in the Earth's atmosphere today comes from photosynthesis by plants and other photosynthetic organisms. They convert carbon dioxide into oxygen as a byproduct, which accounts for approximately 20.95% of the atmosphere.

Oxygen is most commonly found in the air of Earths atmosphere.
