The first organisms that released oxygen into Earth's atmosphere were cyanobacteria, also known as blue-green algae. These microorganisms performed photosynthesis, using sunlight to convert carbon dioxide and water into glucose and oxygen. This process began approximately 2.4 billion years ago during the Great Oxygenation Event, fundamentally changing the planet's atmosphere and paving the way for the evolution of aerobic life forms.
It came from primitive organisms early in earth's history. They were the first organisms to use photosynthesis to make food, by using light to convert Carbon dioxide and water into glucose (food) and oxygen. Since oxygen is a waste product of photosynthesis, it was released into the air. As more and more of these organisms multiplied, large amounts of oxygen were released into the air, forming today's atmosphere.
The first organisms to significantly change Earth's atmosphere were cyanobacteria, which emerged around 2.4 billion years ago. Through the process of photosynthesis, they produced oxygen as a byproduct, leading to the Great Oxidation Event. This increase in atmospheric oxygen transformed the planet's environment, paving the way for the evolution of aerobic life forms.
Cyanobacteria are believed to be responsible for establishing Earth's oxygen-rich atmosphere. Nearly 2.3 billion years ago, these microbes, which lived in the seas, were the first organisms to produce oxygen, leading to the transformation of the Earth's environment.
The first man-made object to leave Earth's atmosphere was the V-2 rocket launched by Germany on October 3, 1942.
Oxygen first entered Earth's atmosphere through the process of photosynthesis by early cyanobacteria and other photosynthetic organisms. These organisms produced oxygen as a byproduct of their metabolic processes, gradually increasing the amount of oxygen in the atmosphere over millions of years.
false
The first oxygen in Earth's early atmosphere was produced by photosynthetic bacteria around 3.5 billion years ago. These bacteria released oxygen as a byproduct of their metabolic processes, gradually increasing the oxygen levels in the atmosphere over millions of years.
Oxygen, now about 20% of the atmosphere, was not part of the original atmosphere of hthe Earth. It was produced by plants, after life developed.
The first source of oxygen in our atmosphere was likely the photosynthesis of cyanobacteria, also known as blue-green algae. Over time, these microorganisms released oxygen as a byproduct of their metabolic processes, gradually increasing the oxygen levels in Earth's atmosphere.
photosynthesis
Oxygen was produced by early photosynthetic organisms, such as cyanobacteria, which released it as a byproduct of photosynthesis. Over time, this oxygen built up in the atmosphere, leading to the levels we have today.

Oxygen. Earth's early(first) atmosphere is believed to contain hydrogen cyanide, carbon dioxide, carbon monoxide, nitrogen, hydrogen sulfide, and water. but still it only had little to no oxygen.
the evolution and proliferation of photosynthetic bacteria and algae around 2.5 to 2.3 billion years ago. These organisms produced oxygen as a byproduct of photosynthesis, leading to the gradual rise of oxygen levels in the Earth's atmosphere.
