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.

Organisms tend to get nutrients like nitrogen, carbon, and phosphorus from their local ecosystem to support essential biological functions such as growth, metabolism, and reproduction. These nutrients are often obtained through processes like decomposition, photosynthesis, and nutrient cycling within the ecosystem.
Oxygen was added to Earth's atmosphere through the process of photosynthesis by early photosynthetic organisms like cyanobacteria. These organisms released oxygen as a byproduct, which accumulated over millions of years and eventually led to the oxygen-rich atmosphere we have today.
Cyanobacteria added oxygen to the atmosphere through the process of photosynthesis, fundamentally changing the composition of Earth's atmosphere and enabling the evolution of aerobic organisms.
Oxygen is primarily added to the air through the process of photosynthesis in plants and algae. During photosynthesis, these organisms use sunlight to convert carbon dioxide and water into oxygen and glucose. This process helps maintain the balance of oxygen in the atmosphere.
The primary sources of oxygen in Earth's early atmosphere were likely photosynthetic organisms like cyanobacteria, which began producing oxygen as a byproduct of photosynthesis. Over time, this oxygen built up in the atmosphere, leading to the development of oxygen-rich conditions on Earth.
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.
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.
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.
The organism added was likely a photosynthetic organism, such as algae or a plant. Photosynthetic organisms use sunlight to convert carbon dioxide and water into oxygen during photosynthesis. The increase in oxygen observed in the test tube is a result of this process taking place.

Oxygen is added to an ecosystem primarily through the process of photosynthesis carried out by plants, algae, and cyanobacteria. These organisms utilize carbon dioxide and sunlight to produce oxygen as a byproduct. Oxygen can also be added to aquatic ecosystems through the process of diffusion from the atmosphere into the water.
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.
