In oxygenic photosynthesis, microbes such as Cyanobacteria use light energy to produce oxygen by combining PSI and PSII a) Why is water a critical component of this process? b) Briefly explain the statement: Not all phototrophs are photosynthetic. c) Would oxygenic and anoxygenic phototrophs likely be found at the same depth within a lake? Why or why not?
