During my two years earning the MBA at the University of Chicago Booth School of Business with a concentration in economics, I thought Iâd follow a path similar to others in my cohort. Iâd earned a law degree, co-founded an innovative startup, and was ready to try something different â I just wasnât sure what. I received offers from banks and consulting firms, but I also received an offer to study abroad for a term at the London School of Economics and Political Science.
Phytoplankton eat small bacteria, which eat decomposing matter. They are in the blue whale's food chain. Most plankton, known as phytoplankton, (but not all) eat in much the same way as do plants - through photosynthesis, the process by which sunlight is converted into food energy. More. Planktonic animals mostly eat other plankton, incluing the planktonic plants described above, and smaller animals which are also plankton.
Within the plankton, holoplankton spend their entire life cycle as plankton (e.g. most algae, copepods, salps, and some jellyfish). By contrast, meroplankton are only planktic for part of their lives (usually the larval stage), and then graduate to either a nektic or benthic (sea floor) existence. Bacterioplankton, bacteria and archaea, which play an important role in remineralising organic material down the water column (note that the prokaryotic phytoplankton are also bacterioplankton). 2  Mycoplankton, fungi and fungus-like organisms, which also are significant in nutrient cycling, as bacterioplankton.
