It is obtained from air. Oxygen is not is not produced in dark reaction but in light reaction
Oxygen gas produced during photosynthesis comes from the splitting of water molecules (H2O) into oxygen (O2) and hydrogen ions (H+). This process, known as photolysis, occurs in the light-dependent reactions of photosynthesis.
Oxygen is produced through the process of photosynthesis by plants, algae, and certain bacteria. During photosynthesis, these organisms use sunlight to convert carbon dioxide and water into oxygen and glucose. This process is essential for maintaining the balance of oxygen in Earth's atmosphere.
The splitting of water by the process of photolysis in photosystem II. There the electrons and protons are used in the process of photosynthesis but oxygen gas is a byproduct that diffuses out of the stomata into the atmosphere.
Glucose comes from the dark reaction of photosynthesis. It is formed by the joining of two PGAL molecules.
The oxygen atoms in CO2 come from the process of photosynthesis in plants. During photosynthesis, plants take in carbon dioxide from the air and water from the soil, and using sunlight as energy, convert them into glucose (sugar) and oxygen.
It is produced by the photosynthesis of plant life.
The oxygen atoms in O2 produced during photosynthesis come from water molecules (H2O) that are split during the light-dependent reactions in the chloroplasts of plant cells. This process, known as photolysis, releases oxygen as a byproduct.
The oxygen we breathe comes from the process of photosynthesis in plants, where they convert carbon dioxide and water into glucose and oxygen. The oxygen gas is released as a byproduct of this reaction.

photosynthesis
Oxygen is one of the by-products of photosynthesis. It comes from the breakdown of water molecules in plants during photosynthesis.
Well, darling, if oxygen decided to take a day off during photosynthesis, we'd all be in a world of hurt. You see, oxygen is kind of a big deal for us living creatures - we need it to breathe and survive. Without oxygen being produced during photosynthesis, we'd be gasping for air faster than you can say "photosynthesis."
Oxygen in water primarily comes from two sources: the atmosphere and photosynthesis by aquatic plants and algae. Oxygen is dissolved into water from the surrounding air, and aquatic plants and algae produce oxygen as a byproduct of photosynthesis, releasing it into the water.
Oxygen which comes from the synthesis of glucose. Oxygen is the by product of 6CO2 + 6H2O to make C6H12O6 releasing three Oxygen (O2) molecules for every molecule of glucose produced.
The oxygen atoms in the oxygen gas produced by photosynthesis come from water molecules that are split during the light-dependent reactions. The oxygen molecules released are a byproduct of this process.
The carbon atoms come from the Ribulose biphosphate and CO2 fixation. The oxygen also comes from CO2 fixation. The hydrogen comes from the oxidation of NADPH (which was produced in the light-dependent reaction)
