Plants, trees, and grass put oxygen into the air.

∙ 15y agothe main constituents of living organisms is carbon with first position then oxygen with second hydrogen with third and nitrogen with fourth, the carbon is the most abundant portion in living organism and nitrogen least quantity. The free nitrogen quantity in atmosphere is considerably more.
Carbon dioxide is being released. As you breathe in you inhale fresh oxygen, but as you breathe out your body releases carbon dioxide.

The highest percentage in the Earth's atmosphere is nitrogen, at 78%. Then oxygen(21%) and CO2, 0.9%.
The earths atmosphere has significantly altered over the years. The process of the earth's atmosphere was recognized and evolved 2.7 billion years ago, forming the nitrogen-oxygen atmosphere that exists today. This change enabled the formation and beginning of the ozone layer (which along with magnetic fields) block solar radiation.
The 'photosynthtics'
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.
The organism added to the test tube was likely a photosynthetic organism, such as algae or a plant, that produces oxygen through photosynthesis in the presence of sunlight. The increase in oxygen observed over time is a result of this photosynthetic process where the organism uses sunlight to convert carbon dioxide and water into oxygen and glucose.
Plants, particularly through the process of photosynthesis, release oxygen into the atmosphere as a byproduct. This oxygen is essential for the survival of many organisms, including humans, who rely on it for respiration.
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
Probably ancient cyanobacteria.
The biggest contributer was and is algae.

Plants, specifically through the process of photosynthesis, add oxygen to the atmosphere as a byproduct. During photosynthesis, plants use sunlight to convert carbon dioxide and water into glucose and oxygen. This oxygen is then released into the air through a plant's leaves.
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.
oxygen is added to the atmosphere when plants take in carbon dioxide during cellular respiration
