Not to be a jerk but to clarify...you cant "produce" oxigen. Law of thermodynamics no elements can be made or destroyed.
btw...if i am guessing you mean what tranfers most of the oxygen in the atomosphere...then i say plants due to photosynthesis.
*Note-"transfer" is not a good word but that was the only thing i could come up with.

It is estimated that between 70% and 80% of the oxygen in the atmosphere is produced by marine plants . Nearly all marine plants are single celled, photosynthetic algae.

Photosynthetic organisms in the ocean produce more O2 than the rainforest. Oceanic algea do some too, its the phytoplankton that do most of the work.

Plants. They use the carbon dioxide that we exhale, and expel oxygen into the air.
