Answer:
plankton
Scientists estimate that 50-80% of the oxygen production on Earth comes from the ocean. The majority of this production is from oceanic plankton — drifting plants, algae, and some bacteria that can photosynthesize.
Plankton that are plants, known as phytoplankton, grow and get their own energy through photosynthesis and are responsible for producing an estimated 80% of the world's oxygen.
bonus answer:
Discuss Earth's oxygen resources.
Explain to students that rainforests are responsible for roughly one-third (28%) of the Earth's oxygen but most (70%) of the oxygen in the atmosphere is produced by marine plants. The remaining 2 percent of Earth's oxygen comes from other sources.
What produces 50 of oxygen we breathe?
“Around 50 percent of the oxygen we breathe comes from phytoplankton,” said Brenda María Soler-Figueroa, a marine biologist at the Smithsonian Environmental Research Center. ... Phytoplankton are tiny plants that live on the surface of oceans and lakes.
What produces more oxygen grass or trees?
Wood represents the locking up of the Carbon extracted from CO2 in order to release oxygen. So forests produce lots of wood, they must also produce lots of oxygen ; which is true. Grass on the other hand produces no wood.
Will we ever run out of oxygen?
Most of the breathable oxygen in Earth's atmosphere is supplied by plant life in a process called photosynthesis . We'll run out of it if we cut down too much of the world's forests and kill too much plant life in the oceans. ... As long as we sustain Earth's plant life in sufficient quantity, we won't run out of oxygen.
can we make oxygen ?
The most common commercial method for producing oxygen is the separation of air using either a cryogenic distillation process or a vacuum swing adsorption process. Nitrogen and argon are also produced by separating them from air. ... This method is called electrolysis and produces very pure hydrogen and oxygen.
