microplankton
Quick Summary
Microplankton are microscopic plankton that drift with water currents. They are a vital part of marine and freshwater ecosystems, forming the base of food chains.123
Plankton can be broadly categorized by size:
* Macroplankton: Organisms 1 mm or larger, easily visible.
* Microplankton: Organisms between 0.05 and 1 mm, a mix of phytoplankton (plant-like) and zooplankton (animal-like).3
* Nannoplankton: Organisms smaller than 0.05 mm, primarily phytoplankton.3
Phytoplankton, like diatoms and dinoflagellates, are photosynthetic producers, while zooplankton are consumers. Microplankton are crucial for supporting larger aquatic life and indirectly humans through fisheries.23
