Definition

Context #1 | Noun

marine biology

Plankton refers to a diverse collection of microscopic organisms that drift in the water column of oceans, seas, and freshwater bodies. These tiny creatures include both phytoplankton, which are plant-like and produce energy through photosynthesis, and zooplankton, which are animal-like and feed on other plankton. Plankton form the base of the aquatic food web, serving as essential food sources for larger organisms such as fish and whales. Their populations can be affected by a variety of environmental factors, including temperature, light, and nutrient availability.

Synonyms

aquatic organisms, drifters, microorganisms.

Examples of usage

  • Phytoplankton are crucial for oxygen production.

Origin of 'plankton'

The term 'plankton' originates from the Greek word 'planktos', which means 'that which is made to wander' or 'drifter'. It was first used in the early 20th century to describe the diverse group of organisms that inhabit water columns and are too small to swim against currents. The classification of plankton has evolved over the years, encompassing a wide range of organisms, including bacteria, algae, and small animals. Today, plankton is recognized as a vital component of aquatic ecosystems, influencing both the biological and chemical processes in marine environments. Research has shown that changes in plankton populations can have significant effects on global carbon cycles and climate change. As such, studying plankton has become increasingly important in the fields of oceanography and environmental science.
