The majority of oxygen in the atmosphere come from photosynthesis. Aquatic Cyanobacteria (blue green algae) were the first known organisms to use photosynthesis, before there were land plants. The by product of photosynthesis is oxygen. This increase in oxygen eventually allowed organisms to use respiration as a method of energy production. Thus it allowed for land animals.

How did oxygen become a part of the earths atmosphere and what did this increase in oxygen levels allow?
The oxygen in the atmosphere is the O-Zone which is O3 (Oxygen 3) because of plant life oxygen had increased via photosynthesis, the incease just allowed the ozone to thicken, but sadly due to CFC there are large holes
Why have the levels of carbon dioxide changed since the early earths atmosphere?
The atmosphere has changed because of population increases and lots of factories that produce the gas. Olivia Perli
What heats earths atmosphere?
The sun heats the atmosphere. Solar radiation largely passes through the atmosphere and warms the surface of the earth. The earth then radiates heat up into the lower levels of the atmosphere where greenhouse gases warm. The warmed greenhouse gases then continue to radiate heat in all directions warming the atmosphere and again the earth's surface.
How would a drastic reduction in plant life on earth affect the atmosphere?
levels of oxygen and carbon dioxide would decrease and levels of carbon dioxide would increase.
What are the change in atmosphere that relate to the climate change?
It is the increase in the levels of greenhouse gases, carbon dioxide and methane that are causing more heat to be retained in the atmosphere. This extra heat is global warming, and this is causing climate change.

Does cyanobacteria increase the levels of carbon dioxide in the atmosphere?
true
What will not increase the levels of carbon dioxide in the atmosphere?
Not burning carbon compounds.

What has caused Carbon Dioxide levels to steadily increase since the 1800s?
The burning of fossil fuels (coal & oil) is the primary cause of the increase in carbon dioxide levels in the atmosphere.
What is the increase of carbon dioxide in the atmosphere the biggest contributor to?
An increase in the atmospheric levels of carbon dioxide is the biggest contributor to global warming.

What may increase of carbon dioxide in the earths atmosphere lead to?
contamination of air, overgroth of plants, increased chances of fires, higher sea levels, more carbon dioxide (from fires), lower sea levels as the CO2 gets even higher, eventually if the trend continues you will have either a Mars or Venus left of Earth.
The temperature of the Earth is rising due to the increase of what?
Increased levels of greenhouse gases in the atmosphere are causing global warming.
Would increases in atmospheric levels of carbon dioxide cause the atmosphere to become warmer?
Yes.
How does increase of CO2 levels affect photosynthesis?
Up to a point, an increase of the reactant Carbon dioxide will increase the production of oxygen (increase the rate of photosynthesis). However, it will eventually change the ratio of CO2 and water as the CO2 increases, and the production of oxygen will decrease, (or in other words, the rate of photosynthesis decreases). This is one of the reasons why an increase of CO2 levels in the atmosphere is dangerous, as oxygen levels will decrease.
How would a drastic reduction in plant life on earth affect the atmosphere?
levels of oxygen and carbon dioxide would decrease and levels of carbon dioxide would increase.
