The source of oxygen in our atmosphere is primarily from photosynthesis, a process carried out by plants, algae, and some bacteria. During photosynthesis, these organisms use sunlight to convert carbon dioxide and water into oxygen and glucose. This process is essential for maintaining the oxygen levels in our atmosphere.

Which atmosphere gas is photosynthesis the major source of?

Oxygen is the major source of photosynthesis in the atmosphere. During photosynthesis, plants and other photosynthetic organisms convert carbon dioxide into oxygen through the process of photosynthesis. This oxygen is then released into the air, replenishing the levels in the atmosphere.


The primary source of oxygen for the earth's atmosphere?

The primary source of oxygen in Earth's atmosphere comes from photosynthesis by plants, algae, and some bacteria. During this process, these organisms use sunlight to convert carbon dioxide and water into oxygen and glucose. This oxygen is then released into the atmosphere as a byproduct.

What is the most source of oxygen for the earth atmosphere?

The most significant source of oxygen in Earth's atmosphere is photosynthesis by plants, algae, and cyanobacteria. These organisms take in carbon dioxide and water, using sunlight to produce oxygen as a byproduct. This process has been crucial in maintaining the balance of oxygen and carbon dioxide in our atmosphere for billions of years.


Which of these was the first source of oxygen in our atmosphere?

The first source of oxygen in our atmosphere was likely the photosynthesis of cyanobacteria, also known as blue-green algae. Over time, these microorganisms released oxygen as a byproduct of their metabolic processes, gradually increasing the oxygen levels in Earth's atmosphere.

What is the most aboundant element in earths atmosphere?

I! think the most aboundant element on earth should be oxygen, because it is the only source of life through which we breath in.


What is the source of oxygen in photosynthesis in plants?

The source of oxygen in photosynthesis in plants is water. During the light-dependent reactions of photosynthesis, water molecules are split into oxygen, protons, and electrons. The oxygen is released into the atmosphere as a byproduct of this process.
