Oxygen is produced in photosynthesis by phytoplankton. High phytoplankton growth reflects high rate of photosyntesis which will reduce dissolved CO2 and enhance dissolved O2 in the water.
phytoplankton provide most of the oxygen to earth.
Since phytoplankton perform photosynthesis, and photosynthesis creates oxygen, I'd say oxygen.
Phytoplankton is what gives us as humans oxygen. Without it, we can`t live.
Marine Phytoplankton. Contains over 70% of the world's oxygen.
Dissolve oxygen is when oxygen is dissolved and oxygen is just normal oxygen!
