Cyanobacteria make molecular oxygen in our atmosphere.
Molecular oxygen makes up 42% of Mercury's atmosphere.
Yes, molecular oxygen makes up about 20% of the atmosphere at sea level.
The molecular oxygen in Earth's atmosphere originated from photosynthesis by early microorganisms, primarily cyanobacteria, around 2.5 billion years ago.
yes, it forms about 21% of our atmosphere.
Yes, oxygen makes up 20.9% of the atmosphere.
My atmosphere is the same as your atmosphere since we all live on the same planet. Oxygen makes up about 19.5% of the atmosphere.
Molecular oxygen (O2) entered Earth's atmosphere through the process of photosynthesis by early photosynthetic organisms, such as cyanobacteria, around 2.4 billion years ago. These organisms released oxygen as a byproduct of converting sunlight, water, and carbon dioxide into energy. Over time, the accumulation of oxygen in the atmosphere led to the development of the oxygen-rich atmosphere we have today.
Oxygen makes up about 21% of Earth's atmosphere.
