PLANKTON

Etymology

The term 'plankton' is borrowed from German 'Plankton', coined by German zoologist and marine biologist Victor Hensen. It is derived from the Ancient Greek 'planktós', meaning 'drifter'.

Definition

Plankton refers to a diverse group of organisms that drift in water or air, including microscopic plants and animals, that serve as a vital food source for many marine species. These organisms are unable to actively propel themselves and play a crucial role in marine ecosystems.

Historical Context

The study of plankton dates back to the late 19th century, with Victor Hensen being a pioneer in the field. Plankton research has since expanded, revealing the importance of these organisms in marine food webs and global biogeochemical cycles.

Cultural Significance

Plankton have cultural significance in various societies, symbolizing the interconnectedness of marine life and the delicate balance of ocean ecosystems. They also serve as indicators of environmental health and are studied for their role in climate regulation.

Related Concepts

Plankton is closely related to concepts such as phytoplankton (plant-like plankton) and zooplankton (animal-like plankton). These subcategories further categorize the diverse organisms within the plankton community.
