What does plankton mean in Greek?

What does plankton mean in biology?
Plankton are the diverse collection of organisms found in water (or air) that are unable to propel themselves against a current (or wind). The individual organisms constituting plankton are called plankters.
Why is plankton important?
Phytoplankton account for about half of the photosynthesis on the planet, making them one of the world’s most important producers of oxygen. Phytoplankton rely on nutrients found in their surroundings, such as phosphate, nitrate, and calcium, to thrive.
What is the plural of plankton?

Which organisms are commonly termed as Phytoplanktons?
Some phytoplankton are bacteria, some are protists, and most are single-celled plants. Among the common kinds are cyanobacteria, silica-encased diatoms, dinoflagellates, green algae, and chalk-coated coccolithophores.
What is plankton in real life?
Phytoplankton are tiny plants and zooplankton are mini animals. Phytoplankton are the basis of the food chain for aquatic ecosystems just like plants on land are the basis for food chains in woodland and prairies. Plankton are found in the ocean and in freshwater like our pond.

How do you know if an organism is a plankton?
An organism is considered plankton if it is carried by tides and currents, and cannot swim well enough to move against these forces. Some plankton drift this way for their entire life cycle. Others are only classified as plankton when they are young, but they eventually grow large enough to swim against the currents.
What are the two types of plankton?
There are two main types of plankton: phytoplankton, which are plants, and zooplankton, which are animals. Zooplankton and other small marine creatures eat phytoplankton and then become food for fish, crustaceans, and other larger species.
What is the difference between plankton and benthos?
Plankton differs from other related terms used for various aquatic species, e.g. Benthos – organisms present on the sea bed that are sessile, burrowing, creeping, etc. Planktons are categorised on the basis of lifecycle, size and trophic level.
