Oxygen is one of the products of photosynthesis and is the gas that rose in abundance in the atmosphere due to the process of photosynthesis.
Photosynthetic bacteria produced oxygen, and as they continued to colonize the earth they produced more oxygen. Eventually all the oxygen sinks became saturated, and this resulted in the Great Oxygenation Event (GOE). Aerobic organisms would late evolve and utilize the free oxygen.
The process of photosynthesis has clear evolutionary advantages to plant and bacterial species. First they are able to passively fix their energy sources from abundant atmospheric carbon and the sun's light. This is in contrast to an animal that must gather and actively metabolize already fixed carbon (organic) sources and respire oxygen.

Photosynthesis by plants
Photosynthetic bacteria produced oxygen, and as they continued to colonize the earth they produced more oxygen. Eventually all the oxygen sinks became saturated, and this resulted in the Great Oxygenation Event (GOE). Aerobic organisms would late evolve and utilize the free oxygen.

Animals respire. Plants respire. Fire uses oxygen. Rusting uses oxygen. Oxygen is removed from the atmosphere by 1. respiration 2. combustion and 3. gradual oxidation process at normal temperature and pressure. It is added to the atmosphere by photosynthesis of green plants.
A planet could potentially regain an atmosphere as a result of the emission of gasses from volcanoes. It is highly unlikely that much will be added to the atmosphere of Mars, as volcanic activity appears to have ceased long ago.
Carbon in the atmosphere is added by processes like combustion, decomposition and losses from methane sources. It is removed by photosynthesis and, chemical reaction and dissolving in ocean water. As long as the sources exceed the sinks the carbon will stay (and increase) in the atmosphere. Human activities increase the sources and decrease the sinks.
the rate of photosynthesis increases as sodium bicarbonate is added to it as long as you stay proportionate to the amount of water in the test tube.
Water is added to the atmosphere through a process called evaporation. This happens when the sun heats up water on the surface of the Earth.
Photosynthesizing prokaryotes affected the ancient atmosphere by adding oxygen. In ancient times the oxygen level was .42%, compared to the 21% oxygen level now. Photosynthesizing prokaryotes have made the world livable today.
