Detailed explanation-1: -Scientists estimate that roughly half 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.
Detailed explanation-2: -Oxygen (O2) is evolved during photosynthetic electron transport when water is split by the oxygen-evolving complex to provide protons and electrons to the chloroplastic electron chain, thereby generating ATP and NADPH-the energy source and reducing power for plant metabolism.
Detailed explanation-3: -Photosynthesis is the process by which plants use sunlight, water, and carbon dioxide to create oxygen and energy in the form of sugar.
Detailed explanation-4: -Photosynthesizing algae in the ocean produce around 70% of oxygen in the atmosphere.
