How much of earth's oxygen comes from rainforest?
Actually, rainforests (or any other type of forest) are not a source of net oxygen production. As vegetation grows it creates oxygen from CO2. The carbon is used to build the plant and the oxygen is released, but, when a plant dies the opposite happens. As it decomposes it produces CO2 and absorbs oxygen as the carbon in the plant recombines with the oxygen. In a mature forest, as rainforests are, the growth and decay are in balance and the net production of oxygen is zero. As a forest grows carbon accumulates in its plant material, but, as deforestation occurs there is a net loss of plant material and CO2 is released. The myth that rainforests produce "28% of the world's oxygen" simply is not true.
Which organism produces more than 50 percent of the oxygen in Earth's atmosphere?
Contrary to popular secular belief, tree's don't actually produce the majority of the worlds oxygen, in fact, approximately 91.6% of the worlds oxygen is produced by phytoplankton blooms in the northern hemisphere of the ocean.
How much oxygen does the ocean have?
45 percent of the earths oxygen is produced by our oceans
Oxygen in the ocean comes from?
air and oceanic plants
What process adds oxygen to ocean water?
Recall that plants take carbon dioxide from the air and make oxygen. Ocean plants do the exact same thing.
Why do you say 70 to 80 percent of the oxygen in the atmosphere comes from marine plants in the ocean and you also say 70 percent comes from rain forests?
About 70% of our oxygen is indeed produced by marine plants. The statement about the rain forests is wrong, they are now known to be essentially oxygen neutral, with little or no net oxygen production at all. That's not saying, it isn't worth saving them.
How does life in the ocean get oxygen?
plants "breathe" carbon dioxide which is what animals exhale. the plant life in the ocean provides oxygen for the marine life.
How is photosyntheis in the ocean possible?
Sunlight penetrates the ocean and reaches the plants and leaves which then photosynthesise to produce oxygen to support ecosystems. Also not all types of leaves require high light intensitys in order for photosynthesis to occur.
On what does the Earth rely for oxygen?
Well plants and trees because they are the opposite to us they breath in CD and breath out oxygen!
Does oxygen in the ocean come from the sun and the air?
no the oxygen from the ocean comes from two things algae and plants create oxygen through photosynthisis and water is made mostly of oxygen and a bit of hydrogen
Is these true Oxygen in the ocean comes from the air and oceanic plants?
yes
In what two ways does oxygen enter the ocean?
the air and oceanic plants
