Plants photosynthesise to produce oxygen. They also act as a carbon sink.
I suppose the largest source of oxygen on Earth is the Amazon forest in South America. Amazon forest is five and a half million square kilometers (1.4 billion acres) big. It is currently the world's most important carbon sink.
The Amazon forest is estimated to produce 20% of the world's oxygen supply, excluding all the other plants (e.g. grass).
For that, I suppose this is the largest source of oxygen on our planet.

What are the 4 major components of the earths atmosphere?
The four major components of Earth's atmosphere are nitrogen (78%), oxygen (21%), argon (0.9%), and carbon dioxide (0.04%). These gases help regulate temperature, support life, and protect against harmful radiation.
What kind of graph would you use to find the major gases found in earths atmosphere?
A pie chart or a bar graph are commonly used to represent the major gases found in Earth's atmosphere. These types of graphs effectively show the distribution or composition of gases such as nitrogen, oxygen, and carbon dioxide in the atmosphere.
What caused a major change in the composition of Earths atmosphere?
One major change in the composition of Earth's atmosphere was the Great Oxidation Event about 2.4 billion years ago. This event led to a significant increase in oxygen levels due to the emergence of photosynthetic organisms that released oxygen as a byproduct. This change had a profound impact on the evolution of life on Earth.
The first major source of oxygen gas was?
The first major source of oxygen gas on Earth was likely produced by early photosynthetic bacteria, such as cyanobacteria, through the process of photosynthesis. This process began around 2.3 billion years ago and led to the build-up of oxygen in the atmosphere, known as the Great Oxidation Event.
What is the major source of oxygen for the earths atmosphere is?
Plants
What was the major contributor of oxygen to earths early atmosphere?
photosynthsis
Why are the major gases that make up earths atmosphere?
Nitrogen, Oxygen and Argon make up 99% of the 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.
What is the major source of free oxygen in atmosphere?
Green Plants
WHAT is the major source of energy for earths system?
The sun is the major external source of energy.
Is the atmosphere the major storage area for earths water?
The atmosphere is ONE OF the major storage areas for Earth's waters
Why do people believe that preservation of the Amazon rain forest is a global concern?
People think it is a major concern mainly because it "IS" a major concern for those of us who would like to keep breathing the oxygen in earths atmosphere, and for those who would like their grand children to have free oxygen available via the earths biosphere.
What are the 4 major components of the earths atmosphere?
The four major components of Earth's atmosphere are nitrogen (78%), oxygen (21%), argon (0.9%), and carbon dioxide (0.04%). These gases help regulate temperature, support life, and protect against harmful radiation.
What is a major source of oxygen on which all human life depends on?
A major source of oxygen that all human life depends on is photosynthesis, the process by which plants, algae, and some bacteria convert carbon dioxide and sunlight into oxygen and glucose. These photosynthetic organisms release oxygen into the atmosphere as a byproduct, which humans and other animals rely on for respiration.
Which is the major source of energy for most earths processes?
the sun
What is the major atmosphere by-product of photosynthesis?
Oxygen -Sabrina (:
