Carbon Dioxide
Early forms of phytoplankton (one-celled ocean plants) removed carbon from the Earth's atmosphere and continue to do so.
Cyanobacteria or blue-green algae was the first organism to create oxygen, thereby making life suitable for other organisms.

Organisms which need oxygen are called aerobic organisms or aerobes. The oxygen is used in the process of respiration to release energy from food. Organisms which do not use oxygen in respiration are called anaerobic organisms or anaerobes. See: http://en.wikipedia.org/wiki/Aerobic_organism
The products of photosynthesis is used by organisms because they products are glucose and oxygen. Organisms use the oxygen in cellular respiration and the glucose is used for energy.
carbon, oxygen, and hydrogen
On the basis of oxygen requirement microorganisms are classified asAerobes: organisms that use molecular oxygen as electron acceptor.Anaerobes: organisms that use some molecule other than molecular oxygen as electron acceptor.Facultative organisms : organisms that can use either molecular oxygen or some other chemical compound as electron acceptor.
Yes, respiration rates for large organisms are generally higher compared to small organisms. Large organisms require more oxygen than small organisms.
early organisms created oxygen from other gases in the atomsphere
Photosynthetic cyanobacteria were the first organisms to produce oxygen. The effect of their oxygen production was that the earth became an environment which was suitable for life.
Aerobic organisms use oxygen.
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.
Aerobic organisms require oxygen.
These organisms do not need oxygen. They are called anaerobes.

Organisms use the oxygen they absorb from the air for their cells. The cells need this oxygen in order to carry out their functions.
Fresh milled flour isn't suitable for making bread. Allowing Oxygen in the flour can strengthen and create elasticity in the proteins.
