How much oxygen is in the sea?
Much less than the approximate 21% in the air. Perhaps half that. Fish need a large energy expenditure to strain oxygen from the water. Most of the oxygen produced by phytoplankton, for instance, is vented into the atmosphere.
What is the ratio of the gases in the atmosphere?
The ratio is approxNitrogen : Oxygen : Argon : Carbon Dioxide :: 39000 : 10500 : 465 : 19.
How is oxygen replaced?
Oxygen is replaced through the process of photosynthesis, where plants and other producers take in carbon dioxide and release oxygen as a byproduct. Additionally, oxygen is replenished by the dissolving of oxygen gas from the atmosphere into water bodies.

What makes molecular oxygen in our atmosphere?
Cyanobacteria make molecular oxygen in our atmosphere.
What types of organisms remove oxygen from the atmosphere?
Animals remove oxygen from the atmosphere.
Is the atmosphere partly oxygen?
Yes, oxygen makes up 20.9% of the atmosphere.
What is the approximate percentage of oxygen in the atmosphere?

Why are plants efficient producers?
Photosynthesis is carried on by plants that produce oxygen.This process has replaced all oxygen that is in the atmosphere for more than 2 000 years.
