Answer 2

• The ocean produces 50-80% of the oxygen produced on the planet.
• The bulk of this output comes from oceanic plankton, which includes floating plants, algae, and some photosynthetic bacteria.
• Prochlorococcus, for example, is the tiniest photosynthetic creature on the planet.
• This little microbe, on the other hand, provides up to 20% of the oxygen in our whole biosphere.
• That's more than all of the tropical rainforests on land put together.

• Because the levels of oxygen generated in the water are continually fluctuating, calculating the precise proportion is challenging.
• Satellite imaging can help scientists follow photosynthesizing plankton and estimate the quantity of photosynthesis taking place in the ocean, but it can't give the entire picture.
• Seasonally, and in reaction to variations in the water's nutrient load, temperature, and other variables, the number of plankton fluctuates.
• According to studies, the amount of oxygen in certain regions fluctuates depending on the time of day and the tides.
