photosynthesis & turbulence
only photosynthesis
consumers
Which of the following does NOT explain why there is an OML, or oxygen minimum layer?
limited light stops photosynthesis at this depth
presence of consumers reduces O2 in the water

Organisms move slowly, using less oxygen
Cold water holds onto more O2 at depths
presence of phytoplankton increases O2
Intense water pressure increases O2 solubility
