"The reason is underwater volcanic vents eject minerals which sustain bacteria and plankton, which besides providing food to fish and other organisms also create oxygen, another life-sustaining element."
"Our Earth would not have oxygen in the atmosphere if it were not for plant life, by photosynthesis generating the oxygen that otherwise would oxidize rocks and vanish."
"The ocean provides every other breath, the oxygen that's in every other breath every second breath comes from the ocean." - Danny Washington
"Trees can help by trapping carbon dioxide, one of the most damaging greenhouse gases, from the atmosphere, replacing it with the oxygen we all need."
"50 to 80% of Earth's oxygen comes from the ocean."
"Over billions of years, these tiny creatures inhabited the world’s oceans, releasing more and more oxygen as they multiplied and spread."
"Knowing more about the abundance of phytoplankton will certainly tell us about what they are consuming and what they are producing, and in this case, what they produce is very helpful to us. It's the air we breathe."
"Plants help convert carbon dioxide to oxygen, just like trees."
"The Amazon is often called the lungs of the world as they produce roughly 20% of the Earth's oxygen."
"Sometimes called the lungs of the world due to the amount of oxygen that trees produce there."
"It's known as the lungs of the earth and it produces over 6% of the world's oxygen."
"The entire source of our oxygen is green plants."
"Without plants, we wouldn't have oxygen in the atmosphere."
"Only about 20% of Earth's oxygen comes from plants and trees, so guess where the other 80% comes from? Algae."
"That's where oxygen comes from, that's where food comes from."
"Oxygen, which is a waste gas, and simple sugars like glucose are created."
"In the light-dependent reactions, oxygen, ATP, and NADPH are created."
"The biggest rainforest provides 20% of the oxygen in the entire world."
"The Amazon produces 33% of the oxygen."
"Algae produce about half of the world's oxygen."
"Brown algae generates about 20-50% of oxygen on the earth."
"Trees do something really special; they take in dirty air and change it to clean oxygen, which all people need to breathe."
"When the sunlight hits the algae, it creates oxygen."
"The Amazon rainforest alone is responsible for the production of about 20 percent of Earth's oxygen."
"They pump out 20% of the world's oxygen and produce incalculable tons of fruits and seeds."
"Photosynthesis generates oxygen and organic molecules which are used in cellular respiration."
"Phytoplankton... are responsible for producing over half of the oxygen in the Earth's atmosphere."
"Algae are important because they do provide a source of food for a lot of animals and also produce a lot of our oxygen."
"This is the photosynthesis where plants are turning carbon dioxide and water into sugar and into oxygen."
"The algae have given you the oxygen you breathe and all the food you eat."
"Plants take in and absorb CO2 and produce oxygen."
"The light-dependent stage is responsible for using light to split water, producing oxygen."
"Photosynthesis is going to take water, carbon dioxide, and turn it into oxygen and glucose."
"The ocean produces 70 percent of the oxygen in the atmosphere."
"When photosynthesis takes place in a leaf, oxygen gas is produced."
"Oxygen, which is useful for us because we need to breathe that."
"The effect of light intensity on the rate of oxygen production."
"Without algae, which many of us think of as fairly slimy and disgusting, we wouldn't be able to breathe."
"Somewhere between 50 and 80 percent of earth's oxygen is produced by phytoplankton."
"They produce oxygen that all eukaryotes need to breathe, including animals, fungi, and protists."
"The phytoplankton in our oceans are creating over half the air we breathe."
"Phytoplankton, tiny plants that live in the ocean, are responsible for producing over half of the oxygen in the Earth's atmosphere."
"Scientists estimate 50 to 80% of the oxygen we breathe comes from the ocean."
"The production of one molecule of oxygen required the absorption of 9 to 10 photons."
"Over half of the world's oxygen is produced by phytoplankton in the ocean."
"They're an important component of many ecological functions, like nutrient cycling and oxygen cycles."
