Yes, since any green plant (which happens to include the fern) produces oxygen.
The percentage of oxygen in water, vapors or ice is the same.
Plants have a much slower metabolism than animals, that's why they also live much longer. Oxygen can be so taxing... Edited answer: Because plants can respire anaerobically also and they can meet out oxygen requirement partly from the process of photosynthesis.
If there is no oxygen present, cells can still produce ATP through anaerobic metabolism, specifically through glycolysis. In glycolysis, one molecule of glucose produces a net of 2 ATP molecules. This is the only way for cells to produce ATP in the absence of oxygen.
Mostly due to the fact that plankton produce much of the world's oxygen.
The place with the highest oxygen levels on Earth is typically at sea level, where the atmosphere is thickest. Rainforests and other dense vegetation areas also produce high levels of oxygen due to photosynthesis.
About 60% of our oxygen is produced by phytoplakton.
Pine trees produce approximately 260 pounds of oxygen per year.
35 percent
About 20%
The Amazon produces up to 25 - 30% of the world's oxygen.
Grass produces about half of the oxygen we breathe in a day.
The percentage of oxygen in water, vapors or ice is the same.
depends on how big the tree is the bigger the more oxygen it produces.
There are very few plants in the Atacama so it produces next to no oxygen.
Grass produces about half of the world's oxygen through photosynthesis.
Depends on how much i guess, but...magnesium oxide?
A mature cherry tree can produce around 200 pounds of oxygen per year, which is enough to sustain two adult humans.
