 Heterotrophic picoplankton

Heterotrophic picoplankton refers to a group of microscopic organisms that are typically less than 2 micrometers in size and are primarily non-photosynthetic. These organisms play a crucial role in the aquatic ecosystem by feeding on organic matter, including bacteria and dissolved organic carbon. Heterotrophic picoplankton includes a variety of microorganisms such as bacteria and archaea that are involved in nutrient cycling and energy flow within marine and freshwater ecosystems.
