Yes they are; diatoms are the main source of oxygen in the universe.
Diatoms are the major primary producer in the globe. They produce oxygen more than the all the world tropical forests put together. Whatever the oxygen taken inside by us are atleast 1/4 of its from diatoms. Recently freshwater diatoms are also used as bioindicators, to detect the pollution.
Diatoms
Algae provides much of the earth's oxygen and their skeletons (especially diatoms) build up to make certain limestone.
About 60% of our oxygen is produced by phytoplakton.
Hemoglobin present inside the RBCs provides oxygen to the tissues when the RBCs reach them via the capillaries
0.01 percent of the worlds oxygen is from the amazon
Oxygen = O2Nitrogen = N2Carbon Dioxide = CO2First to are diatoms and the third is a molecule of CO2
The Amazon produces up to 25 - 30% of the world's oxygen.
About 20%
autotrophic- meaning they produce there own food through photosynthesis
The percentage of oxygen in water, vapors or ice is the same.
