What was the impact that the addition of oxygen to the atmosphere had on the organisms that lived on earth?

To the organisms that produced the oxygen as a waste gas of a anaerobic metabolism, the impact was bad and severely impacted them to the point of extinction. They are now the extremeophiles.
To the developing anaerobes of the seas this addition of great amounts of oxygen was the impetus to their adaptive radiation all through the oceans of the earth.
No until plants emerged did gas exchange change somewhat again.

How would the increasing number of photosynthesizing organisms on earth have affected both earth and its other organisms?
As the first photosynthetic organisms increased in number, the concentration of oxygen in Earth's atmosphere began to increase. Organisms that could respire aerobically would have evolved and thrived. The sun's rays would have converted much of the oxygen into ozone molecules that would then have formed a layer that contained more ozone than the rest of the atmosphere.
What was the response of the various groups of early organisms that existed when oxygen levels rose in the atmosphere?
It drove some life forms to extinction.
Can all members of the domain Archaea survive only in the absence of oxygen?
All cells exist in oxygen in some way. Some organisms gain oxygen from the atmosphere while others use oxygen from carbohydrates and other forms of sustenance.
What other organisms make air?
No organisms make "air." Air is the natural atmosphere of the earth. Most of it is nitrogen. Most plants take in carbon-dioxide, and produce oxygen. Most animals take in oxygen, and produce carbon dioxide.
What is Organisms that live on land get there oxygen from?
From photosynthesis. It's a waste product, but some of it are used in cellular respiration.
What types of organisms remove oxygen from the atmosphere?
Animals remove oxygen from the atmosphere.
Did organisms that require oxygen exist before photosynthetic organisms?
It would be impossible for oxygen requiring organisms to exist before photosynthetic organisms because there was not oxygen in the atmosphere for these organisms to breathe. Photosynthetic organisms take carbon dioxide and water in and create oxygen as waste. Before these photosynthetic organisms existed there was not enough or any oxygen in the atmosphere for organisms requiring oxygen to survive.
What is the process when organisms add oxygen to the atmosphere called?
photosynthesis
What organisms contributed the most to the shift between an oxygen-free atmosphere to an oxygenated atmosphere?
The 'photosynthtics'
What organisms contributed the most to the shift between an oxygen free atmosphere to an oxygenated atmosphere?
cyanobacteria
What organisms contribute the most to shift between an oxygen free atmosphere to an oxygenated atmosphere?
cyanobacteria
What gas has had the greatest impact on life on earth?
More than a billion years ago, the rise of oxygen-releasing photosynthetic cells changed the course of evolution by enriching the atmosphere with this gas organisms has often come at the expense of others. Oxygen has the greatest impact on life, with oxygen life would not exists.
Does photosynthesis add oxygen to the atmosphere?
Yes, photosynthasis does add oxygen to the atmosphere becaause the organisms (plants) developed the ability to photosynthasise. By taking in carbon dioxide and releasing oxygen.
What is inferred to be the main source of the free oxygen that first entered earth's atmosphere?
oxygen producing organisms
Why is oxygen such an important part of the earth's atmosphere?
Oxygen is necessary for most organisms to carry out their life functions.
Does oxygen can enter the atmosphere during cellular respiration or photosynthesis?
Oxygen can enter the atmosphere during celluar respiration, because if it enters photosynthesis, how about the other organisms?
Which of these statements is true about the oxygen revolution?
Cyanobacteria were the first organisms to produce oxygen in water, which then escaped into the atmosphere.
