Where did most of earths atmospheric oxygen originally come from?
Most of Earth's atmospheric oxygen originally came from photosynthesis by early cyanobacteria and other photosynthetic organisms around 2.5 billion years ago. These organisms converted carbon dioxide and water into oxygen through the process of photosynthesis, gradually increasing oxygen levels in the atmosphere.
What produces most of the earths atmospheric oxygen?
The majority of Earth's atmospheric oxygen is produced by marine phytoplankton through the process of photosynthesis. These microscopic organisms play a crucial role in the oxygen cycle by converting carbon dioxide and sunlight into oxygen.
What are the 3 most common elements that make up the gases in out earths atmosphere?
These gases are nitrogen, oxygen and argon.
How does oxygen effect the of organisms?
Oxygen is essential for cellular respiration in organisms, where it is used to produce energy. Without oxygen, most living organisms would not be able to survive. However, prolonged exposure to high levels of oxygen can also be toxic to certain organisms, causing damage to cells and tissues.
What are organisms which need oxygen to survive?
Organisms that need oxygen to survive are known as obligate aerobes. These organisms require oxygen for their metabolism and cellular respiration to produce energy. Examples include humans, most animals, and many types of bacteria.
Why and how can only 6 elements make up most of earths biomass?
because the six elements ( carbon, nitrogen, oxygen, phosphorus, and sulfur) are required by many organisms and some of those elements make up our air
What three elemenst make up most of the earths crust?
Silicon, oxygen and nitrogen

Is most of the earths atmosphere covered with oxygen?
no
Name three elements that make up most of earths mantle?
The rocks in earths mantel are made up of 44.8% oxygen, 21.5% silicon, and 22.8% magnesium. Iron, calcium, sodium, aluminum, and potassium are also present. The elements occur in rocks as oxides.
Which of the earths layers has the most air?
The Crust has the most oxygen in it
What is oxygen most commonly found in?
Oxygen is most commonly found in the air of Earths atmosphere.
What produces most of the earths atmospheric oxygen?

Which group of organisms is most responsible for changing the compisition of earths early atmosphere?
Cyanobacteria are the group of organisms most responsible for changing the composition of Earth's early atmosphere. Through photosynthesis, they released oxygen into the atmosphere, fundamentally altering its composition and paving the way for aerobic organisms to evolve.
What are the most common elements that make up organisms?
COHN - Hydrogen, oxygen, carbon, & nitrogen.
What are the four elements that make up over percent of the body in most organisms?
Hydrogen,oxygen, nitrogen, and carbon (in that order) make up over 95 percent of the body of most organisms.
Most of earths dry is made up of what?
nitrogen and oxygen
