  • Diversity of plankton and quantitative methods for each taxon

    • What is plankton?


      Marine organisms are broadly divided into three categories according to their lifestyles.

      Nekton： Living in water and capable of swimming against the stream

      Bentus：An organism that lives in the seabed

      In addition,

      Plankton is a living organism that lives in water and has poor swimming ability.

  • Examples of Volume-Carbon Relationships Different for Each Classification Group


    • Because plankton is defined as "not swimming against flow, but drifting," it includes viruses in the small, and ethizen jellyfish in the large, and ranges in size from 1 to 10,000 times. They are also diverse as taxa and include heterotrophic bacteria, plants and animals, each with different roles within ecosystems. Many nectons also live as planktons in eggs and larvae.
