The ocean produces about 50-85% of the Earth's oxygen, primarily through photosynthesis by phytoplankton and algae. This oxygen comes from plants and algae using sunlight, carbon dioxide, and water to produce oxygen during the process of photosynthesis.
Approximately 50-80% of the planet's oxygen is produced by the ocean, primarily through photosynthesis by phytoplankton, seaweed, and other marine plants. This process releases oxygen into the water and atmosphere, contributing significantly to the Earth's oxygen supply.
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.
It is estimated that 50-85% of Earth's oxygen production comes from phytoplankton in the ocean, particularly in the areas of the ocean where sunlight reaches the surface and allows for photosynthesis to occur. Forests and other land plants also contribute significantly to the production of oxygen on Earth.
Oxygen is found at high levels near the surface of the ocean due to plant photosynthesis. Plants in the ocean, like phytoplankton, produce oxygen as a byproduct of photosynthesis, leading to high concentrations of oxygen in the surface waters.
The largest producer of oxygen on Earth is phytoplankton. These tiny marine plants produce a significant amount of the planet's oxygen through photosynthesis in the ocean. Additionally, forests and other terrestrial plants are also major contributors to global oxygen production.
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.
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.
air and oceanic plants
Earth relies on photosynthesis, primarily carried out by plants and phytoplankton, to produce oxygen. These organisms use sunlight to convert carbon dioxide and water into glucose and oxygen. Approximately half of the oxygen we breathe comes from phytoplankton in the oceans.
Yes, oxygen in the ocean primarily comes from photosynthesis by marine plants and phytoplankton, fueled by sunlight. Around half of Earth's oxygen is produced by oceanic photosynthesizers. Atmospheric oxygen also dissolves into the water at the ocean's surface.
plants "breathe" carbon dioxide which is what animals exhale. the plant life in the ocean provides oxygen for the marine life.
