Scientists agree that significant amounts of oxygen were first put into the atmosphere by cyanobacteria which used and still use a process called photosynthesis to convert carbon dioxide and water into sugar and oxygen. The sugar is then used to build cell walls and in the metabolism. When plants evolved, they too carried out photosynthesis, putting even more oxygen into the atmosphere. Prior to the evolution of cyanobacteria, the metabolisms of organism relied on anaerobic processes.
What else can I help you with?
Where did the oxygen in Earth's atmosphere come from originally?
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.
Billions of years ago how did the earth come to have an oxygen rich atmosphere?
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.
Where did water in the ocean come from and how did oxygen get into the atmosphere?
The water in the ocean primarily comes from the Earth's interior, released through volcanic activity. Oxygen entered the atmosphere through the process of photosynthesis, where early photosynthetic organisms released oxygen as a byproduct. Over time, this oxygen built up in the atmosphere, leading to the oxygen-rich environment we have today.
How did free oxygen come about in the atmosphere?
Free oxygen accumulated in Earth's atmosphere around 2.4 billion years ago due to the process of photosynthesis by early cyanobacteria. These organisms produced oxygen as a byproduct of converting sunlight and carbon dioxide into energy. Over time, oxygen levels increased, leading to the oxygen-rich atmosphere we have today.
What are two resources that come from the atmosphere and describe how both are used?
Two resources that come from the atmosphere are oxygen and helium. Oxygen is used by humans and animals for respiration, while helium is used in various applications like filling balloons, airships, and in cryogenics for cooling superconducting magnets.
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.
Where did the oxygen in Earth's atmosphere come from originally?
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.
Where do the oxygen molecules in the atmosphere come from?
Oxygen molecules in the atmosphere primarily come from plants and other photosynthetic organisms that release oxygen during the process of photosynthesis. This process involves the conversion of carbon dioxide and water into glucose and oxygen. Additionally, a smaller amount of oxygen also comes from the breakdown of carbon dioxide molecules in the upper atmosphere by solar radiation.
Where does the oxygen that plants release into the atmosphere come from?
It is the Oxygen from the CO2 and H2O tat they use to make sugars.
Does air come from the sun?
No. Earth's atmosphere most likely originate from volcanic atmosphere. The oxygen is produced by plants.
Where did oxygen come from in the ocean?
It is diffused from the air, in the atmosphere, and from plant life in the ocean.
Billions of years ago how did the earth come to have an oxygen rich atmosphere?
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.
Where does the free oxygen it the atmosphere come form today?
It is produced by the photosynthesis of plant life.
Where did water in the ocean come from and how did oxygen get into the atmosphere?
The water in the ocean primarily comes from the Earth's interior, released through volcanic activity. Oxygen entered the atmosphere through the process of photosynthesis, where early photosynthetic organisms released oxygen as a byproduct. Over time, this oxygen built up in the atmosphere, leading to the oxygen-rich environment we have today.
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.
How did free oxygen come about in the atmosphere?
