Indeed not so simple to answer. It varies from species to species, and also we shouldn't forget trees need oxygen to survive. For example, the amazon forest, once believed to be the 'lung of the planet', consumes all the oxygen it produces. Of course it is important in other ways. So yeah, the most important source of oxygen in the atmosphere are microorganisms in the ocean.

A mature leafy tree produces as much oxygen in a season as 10 people inhale in a year.

A single mature tree can absorb carbon dioxide at a rate of 48 lbs./year and release enough oxygen back into the atmosphere to support 2 human beings.
McAliney, Mike. Arguments for Land Conservation:Documentation and Information Sources for Land Resources Protection, Trust for Public Land, Sacramento, CA, December, 1993
Based on the above estimates of oxygen consumption and net oxygen production by an acre of tree cover in Brooklyn, one ACRE of trees would produce enough oxygen for 14 people

"A single mature tree...releases enough oxygen back into the atmosphere to support 2 human beings"
don't know how accurate it is, but it's a lead

rule of thumb, one big tree to offset the oxygen intake of one person

95% of our oxygen comes from the ocean, so it is hard to tell.
