Algae. Their net release of oxygen is greater than the amount produced by all land-based plants together.
Most of the Earth's oxygen is produced by plants, both on surface and under water.

The earths crust is 28.5% Oxygen, so when Trees & plants grow the oxygen from the crust will lead into the plants, which will start the cycle of Respiration & Photosynthesis.

It is none other than our own planet Earth, which has nitrogen and oxygen in its atmosphere.
What planet is the planet of oxygen?
The Earth is the only planet with a large quantity of free oxygen, which came about because of plant life, which uses carbon dioxide and energy from the Sun to manufacture carbon for plant tissues, giving out oxygen as a waste product. About 21% of the Earth's atmosphere is oxygen.
What are the examples of organ?
The simpelest answer would be anything on this planet that uses oxygen to live, or produces oxygen by living, and butoth of which produce wast material.

What produces the most oxygen you need?
the ocean produces the most oxygen we need
How big is a tree before it produces oxygen?
It at least has to be a sprout before it produces oxygen.
How does pond weed get oxygen?
Yes, pond weed produces oxygen, because it photosynthesises. The oxygen can be seen as bubbles
Photosynthesis ultimately produces almost all of the food on the planet. More than 250 billion metric tons of sugar are produced via photosynthesis each year. Most of the oxygen on our planet is also?
It seems likely that all the oxygen in the Earth's atmosphere was produced by photosynthesis. Before photosynthetic plants evolved, the atmosphere had little or no oxygen, as judged by geological evidence.
Which process produces oxygen gas in the oxygen cycles?
Photosynthesis
Do any of the planet have oxygen in their atmosphere?
Yes. There is one planet with oxygen in its atmosphere: our home planet Earth.
What is the gas that peroxide produces?
Oxygen
Burning coal produces which gas?
Burning coal in complete combustion of oxygen produces carbon-dioxide where as burning coal in limted amount of oxygen produces carbon-monoxide.
