Oxygen in the atmosphere primarily comes from photosynthesis by plants and other photosynthetic organisms. These organisms use sunlight to convert carbon dioxide into oxygen as a byproduct. Over millions of years, this process has led to the accumulation of oxygen in the Earth's atmosphere.
What else can I help you with?
What is the oxygen content of the atmosphere?
The atmosphere is 79.9% oxygen.
What is the proportion of oxygen in the atmosphere today?
About 21% of the Earth's atmosphere is oxygen.
What do scientist think was the source of the oxygen in earths atmosphere?
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.
What atmosphere we live on?
The main components of Earth's atmosphere are nitrogen and oxygen. Of these, oxygen is the one we can't live without.
Do trees provide the most oxygen for the atmosphere?
While trees play a significant role in producing oxygen, they are not the sole source. Phytoplankton, algae, and other plants also contribute to oxygen production in the atmosphere through photosynthesis. Overall, terrestrial and aquatic ecosystems collectively contribute to the oxygen balance in the atmosphere.
What came first oxygen or life?
Life came first. The oxygen in Earth's atmosphere is a product of living organisms carrying out photosynthesis.
Which came first anaerobic or aerobic?
Anaerobic came first, because there was no oxygen in the Earth's original atmosphere.
Where did the oxygen and ozone in your atmosphere come from according to this theory?
Oxygen when came in contact with UV broke down. It then reacted with more oxygen to form ozone.
How did earth come have an oxygen atmosphere?
Early organisms created oxygen from other gases in the atmosphere. More specifically, the methane atmosphere on Earth was supplanted by oxygen generated by microorganisms in the oceans. Today, the vast majority of our oxygen comes from the ocean - mainly plants. Earth came to have a oxygen atmostphere because that is the way God invisoned it, so thats how he made it.
Which came first Eukaryotes or oxygen Accumulation in the Atmosphere?
Oxygen accumulation in the atmosphere came before Eukaryotes. Around 2.4 billion years ago, photosynthetic bacteria began to produce oxygen as a byproduct of photosynthesis, leading to the Great Oxidation Event. Eukaryotes, which possess specialized organelles like mitochondria that utilize oxygen for energy production, evolved around 2 billion years ago.
What percent of the atmosphere is oxygen'?
21% of the atmosphere is oxygen.
What is the oxygen content of the atmosphere?
The atmosphere is 79.9% oxygen.
What is an aerobic atmosphere?
the environment which has the availability of oxygen it is called aerobic atmosphere and if the availability of oxygen is not there in atmosphere then it is anaerobic type We live in a aerobic atmosphere which has the oxygen available
Is there oxygen in Mercury?
No, there is no oxygen in Mercury's atmosphere because Mercury does not have an atmosphere.
What is the proportion of oxygen in the atmosphere today?
About 21% of the Earth's atmosphere is oxygen.
What gives more oxygen to the atmosphere?
Plankton gives more oxygen to the atmosphere.
What types of organisms remove oxygen from the atmosphere?
Animals remove oxygen from the atmosphere.
