Turbulence. Waves and currents create many small eddies under the surface. These stir the water and can move plankton cells up towards the light or down into the dark. Turbulence moves plantkon much faster than they can sink or swim.
do plants perform photosynthesis at night
At night, when photosynthesis can’t take place, plants continue to consume oxygen but they don’t release any back into the room. Would that mean that plants really do compete with humans for oxygen?
They can't photosynthesise in dark ..
I have koi in outside fish ponds. At times during the long summer days there is an occurrence called an algae bloom where the water in the pond becomes filled with very small suspended algae. During the day there is no problem with the respiration of the koi that I have in the pond… but because the algae use up so much available oxygen during the night and do not add any O2 to the water…my koi in the very early morning hours before the sunlight starts photosynthesis of the algae run out of the amount of oxygen they need for respiration and are forced to breathe atmospheric O2 at the surface of the pond! They gasp for O2 out of the water from the atmosphere where there is enough available for them to survive. My point is in water ponds there is a semi closed environment where plants can use up so much oxygen at night that they force the fish to get their oxygen elsewhere. When days become shorter the algae bloom will naturally diminish if I wait it out and do not do massive water changes or resort to killing the floating algae with a chemical plant killer algaecide that will not kill my fish if used in the proper doses. Plants do use O2 at night and do not give off any O2 in darkness!
