Where does oxygen come from and why is it important to life on earth?
Oxygen is important as it the breathing sources. It also forms ozone which is vital for life on earth.
How did early bacteria in the earths shallow seas contribute to the development of life on earth?
They PHOTOSYNTHESIZED
Why are phytoplankton and bacteria important to life on earth?
Mostly due to the fact that plankton produce much of the world's oxygen.
The oxygen content in the atmosphere of the early Earth is thought to have increased significantly once which developed -Mitochondria - Photosynthetic bacteria - Amino acids - Archaebacteria?
Photosynthetic bacteria
What was the significance of the development of chloroplasts?
The development of chloroplasts led to the oxygenation of Earth's atmosphere, which allowed the evolution of more complex oxygen-breathing organisms.
How did earth get oxygen 4 billion years ago?
From primitive bacteria that produced oxygen as a waste product.

Suggest an explanation for the importance of oxygen in the early stage of chemistry's development?
Oxygen was important in the early stage of chemistry's development because of the fundamental roles of air (including oxygen) in the life of a human and the process of combustion. The earliest elements defined included air, along with earth, water, and fire.

Earliest forms of life on earth?
the were archbacteria they were the simplest bacteria and didn't use oxygen
What is the specific name of the one organism on earth that does not use oxygen it its respiratory system?
There exist several life forms which do not need oxygen for survival, for example bacteria purple sulfur bacteria (Chromatiales). But if I recall correctly, no higher life forms which don't need oxygen exist on Earth.
What would happen if there was no oxygen on earth?
Some Bacteria do not need and will even die in the presence of oxygen. They would thrive and probably evolve.
What are carbon dioxide planets?
Both Venus and Mars have carbon-dioxide atmospheres. The Earth also started with a carbon-dioxide atmosphere but the development of anerobic bacteria produced oxygen as a waste-product which eventually altered the atmosphere and killed off the bacteria but allowed other types of organism using oxygen to develop, and that eventually led to animal life.
What important gas was missing from early earth?
oxygen
What is the most important element found on Earth?
oxygen
What are facts for oxygen?
Oxygen makes up only 21% of the air we breathe, but it is certainly the most important part, since we can't live without it.The Earth's atmosphere initially had very little oxygen; oxygen was added to the atmosphere by living things (anaerobic bacteria at first, plants later).The oxygen that we breathe now is produced by bacteria, algae and plants. It is estimated that 70 to 80% of the oxygen in the atmosphere comes from aquatic plants in the oceans.
What is the most important component of the oxygen we breath on earth?
Oxygen is itself a chemical element.
