Plankton are the diverse collection of organisms that drift in water (or air) but are unable to actively propel themselves against currents (or wind). [1][2] The individual organisms constituting plankton are called plankters. [3]

2025年4月2日 · Plankton, marine and freshwater organisms that, because they are nonmotile or too small or weak to swim against the current, exist in a drifting state. Plankton is the productive base of both marine and freshwater ecosystems, providing food …

2023年3月29日 · Plankton is the collection of organisms that drift with tides and currents. Two important groups are phytoplankton (plant-like) and zooplankton (animal-life), but plankton include species from all the kingdoms of life, plus viruses.

2019年8月9日 · Plankton are a group of marine and freshwater organisms that drift along ocean currents because they are too small or weak to swim against them. Their name comes from …

What is plankton? Plankton are a collection of tiny organisms that live at and beneath the surface of lakes, rivers, ponds, and oceans across the planet.

Planktons are microscopic entities constituting the sustaining base of food chains in the ocean. They live their lives drifting in the water column. “Plankton” term is used for all the organisms found in marine as well as freshwater, which are non-motile and cannot swim against the water current. They are drifted by water currents.

2025年3月17日 · These microbes thrive on nutrients in seawater and are often photosynthetic. The plankton include a wide variety of organisms such as algae, bacteria, protozoans, the larvae of some animals, and crustaceans. A large proportion of the plankton are protists —i.e., eukaryotic, predominantly single-celled organisms.

2023年10月19日 · There are two main types of plankton: phytoplankton, which are plants, and zooplankton, which are animals. Zoo plankton and other small marine creatures eat phyto …

2011年4月18日 · When you go swimming in a lake or in the ocean, each stroke pushes you past billions upon billions of microscopic creatures called plankton. It was a German scientist named Viktor Hensen who gave plankton this name.
