Plankton have traditionally been categorized as producer, consumer, and recycler groups, but some plankton are able to benefit from more than just one trophic level. In this mixed trophic strategy—known as mixotrophy—organisms act as both producers and consumers, either at the same time or switching between modes of nutrition in response to ...
Phytoplankton (/ ˌ f aɪ t oʊ ˈ p l æ ŋ k t ə n /) are the autotrophic (self-feeding) components of the plankton community and a key part of ocean and freshwater ecosystems.The name comes from the Greek words φυτόν (phyton), meaning 'plant', and πλαγκτός (planktos), meaning 'wanderer' or 'drifter'.
A multicellular, glandular hair that usually produces a mucilaginous substance and is located on sepal s, stipules, or petioles, or on nearby parts of stem s; commonly found on plants in the order Gentianales. columella In flowering plants, the central axis of the cone or fruit, e.g. in Callitris. column 1.
Zooplankton can be contrasted with phytoplankton (cyanobacteria and microalgae), which are the plant-like component of the plankton community (the "phyto-" prefix comes from Ancient Greek: φῠτόν, romanized: phutón, lit. 'plant', although taxonomically not plants).
Plankton comes in all sizes and shapes, from microscopic to several inches. Some larger jellyfish are considered planktonic. Plankton are the building blocks of life in the sea. Everything depends ...
A planktivore is an aquatic organism that feeds on planktonic food, including zooplankton and phytoplankton. [1] [2] Planktivorous organisms encompass a range of some of the planet's smallest to largest multicellular animals in both the present day and in the past billion years; basking sharks and copepods are just two examples of giant and microscopic organisms that feed upon plankton.
However, there is a simpler scheme that categorizes plankton based on a logarithmic size scale: Macroplankton (200–2000 μm) Micro-plankton (20–200 μm) Nanoplankton (2–20 μm) This was even further expanded to include picoplankton (0.2–2 μm) and fem-toplankton (0.02–0.2 μm), as well as net plankton, ultraplankton.
The word "neuston" comes from Greek neustos, meaning "swimming", and the noun suffix-on (as in "plankton"). [2] This term first appears in the biological literature in 1917. [3] The alternative term pleuston comes from the Greek plein, meaning "to sail or float". The first known use of this word was in 1909, before the first known use of ...
