Part of the contents of one dip of a hand net.The image contains diverse planktonic organisms, ranging from photosynthetic cyanobacteria and diatoms to many different types of zooplankton, including both holoplankton (permanent residents of the plankton) and meroplankton (temporary residents of the plankton, e.g., fish eggs, crab larvae, worm larvae).
Phytoplankton (/ ˌfaɪtoʊˈplæŋktən /) 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'. [1][2][3] Phytoplankton obtain their ...
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.
Marine diatoms are among the many planktonic organisms that paradoxically appear to flout the competitive exclusion principle.. In aquatic biology, the paradox of the plankton describes the situation in which a limited range of resources supports an unexpectedly wide range of plankton species, apparently flouting the competitive exclusion principle, which holds that when two species compete ...
Oceanic physical-biological process. Due to the higher density of sea water (1,030 kg m −3) than air (1.2 kg m −3 ), the force exerted by the same velocity on an organism is 827 times stronger in the ocean. When waves crash on the shore, the force exerted on littoral organisms can be equivalent to several tons.
Planktology is the study of plankton, various small drifting plants, animals and microorganisms that inhabit bodies of water. Planktology topics include primary production, energy flow and the carbon cycle . Plankton drive the "biological pump", a process by which the ocean ecosystem transports carbon from the surface euphotic zone to the ocean ...
Plankton. Zooplankton are the heterotrophic component of the planktonic community (the "zoo-" prefix comes from Ancient Greek: ζῷον, romanized: zôion, lit. 'animal'), having to consume other organisms to thrive. Plankton are aquatic organisms that are unable to swim effectively against currents.
