...(Isoetes macrospora), use only carbon dioxide in photosynthesis and thus are restricted to soft water.
Using Carbon and Oxygen Photosynthesis and respiration in dense beds can alter the chemical com- position of lake water. Photosynthesis enables green plants to convert carbon dioxide...
Photosynthesis removes carbon dioxide from lake water and...
...1% of surface light is available for photosynthesis (Davis and Brinson 1980). At this depth, light availability allows just enough photosynthesis to compensate for respiration in lab studies...
