Earth's atmosphere became rich in oxygen through a process called photosynthesis, where plants and other organisms use sunlight to convert carbon dioxide and water into oxygen and energy-rich molecules like sugars. Over billions of years, these photosynthetic organisms gradually built up oxygen levels in the atmosphere, leading to the oxygen-rich environment we have today.
Earths atmosphere is rich in Oxygen, some 21% of the air is Oxygen. There is oxygen on other planets, but the percentage comes nowhere close to this. The percentage of Oxygen in earths atmosphere is thought to have been much higher in the past, before animals were about, but after the arrival of plants.
Oxygen was added to Earth's atmosphere through the process of photosynthesis by early photosynthetic organisms like cyanobacteria. These organisms released oxygen as a byproduct, which accumulated over millions of years and eventually led to the oxygen-rich atmosphere we have today.
Earth's atmosphere is rich in nitrogen (78%) and oxygen (21%) due to their abundance in the Earth's crust and the chemical reactions that have occurred over billions of years. Nitrogen is released from volcanic activity and decay of organic matter, while oxygen is produced through photosynthesis by plants and algae. These gases also contribute to the stability of Earth's atmosphere.
Oxygen in Earth's atmosphere was produced through the process of photosynthesis by cyanobacteria and early algae, starting around 2.5 billion years ago. These organisms converted carbon dioxide and water into glucose and oxygen using sunlight as an energy source. This oxygen began accumulating in the atmosphere and eventually led to the development of the oxygen-rich atmosphere we have today.
Oxygen became part of Earth's atmosphere mainly as a result of the evolution of life forms, particularly through photosynthesis by early cyanobacteria and plants. This process involved converting carbon dioxide into oxygen as a byproduct, leading to the oxygen-rich atmosphere we have today.

The primary sources of oxygen in Earth's early atmosphere were likely photosynthetic organisms like cyanobacteria, which began producing oxygen as a byproduct of photosynthesis. Over time, this oxygen built up in the atmosphere, leading to the development of oxygen-rich conditions on Earth.

The evolution of photosynthetic bacteria and later on, plants, was responsible for changing the formerly poisonous atmosphere to an oxygen-rich one we have today. These organisms released oxygen as a byproduct of photosynthesis, gradually increasing levels of oxygen in the atmosphere.
the quality of our blood that rich with oxygen will become low
The oxygen in Earth's atmosphere was likely produced around 2.4 billion years ago by photosynthetic organisms such as cyanobacteria, which released oxygen as a byproduct of photosynthesis. Over time, this oxygen accumulated in the atmosphere, leading to the development of an oxygen-rich environment.
Early photosynthetic bacteria, such as cyanobacteria, were responsible for changing the formerly poisonous atmosphere to an oxygen-rich atmosphere through the process of photosynthesis. These organisms released oxygen as a byproduct of converting sunlight into energy, which gradually increased the atmospheric oxygen levels over time.
The development of photosynthetic organisms, such as cyanobacteria and plants, played a significant role in changing Earth's atmosphere to oxygen-rich. These organisms released oxygen as a byproduct of photosynthesis, gradually increasing the oxygen levels in the atmosphere over millions of years.
The oxygen in Earth's atmosphere originally comes from the process of photosynthesis carried out by early photosynthetic organisms like cyanobacteria, which released oxygen as a byproduct. Over time, the accumulation of oxygen led to the development of an oxygen-rich atmosphere.
