![]() These are all examples of organisms that form nektons. Think of some of the most popular marine life that humans eat - crabs shrimp and tuna for instance. Individual organisms that form nektons are generally high on the food chain ecologically and some of their main predators are humans. Plankton are primarily divided into broad functional (or trophic level) groups: Phytoplankton (from Greek phyton or plant) are autotrophic prokaryotic or eukaryotic algae that live near the water surface where there is sufficient light to support photosynthesis. … They are tiny microscopic plants called phytoplankton. Since they make or produce their own food they are called producers. Using the energy from the sun water and carbon dioxide from the atmosphere and nutrients they chemically make their own food. Plants make their own food through a process called photosynthesis. “There are about 11 000 formally described species of plankton – we have evidence for at least 10 times more than that.” Why is plankton a producer? Benthos are aquatic organisms that crawl in sediments at the bottom of a body of water. Examples of nekton include fish and shrimp. Nekton are aquatic animals that can move on their own by “swimming” through the water. See also what is geographic preference What is a nekton benthos? Molluscan nekton are animals like octopus and squid. This group includes bony fish whales sharks turtles snakes eels porpoises dolphins and seals. The largest group of nekton are chordates and have bones or cartilage. These two types of planktons float on water surfaces. Other Crustaceans krills are examples of zooplanktons algae and diatoms are examples of phytoplanktons. What is zooplankton and phytoplankton?ĭifference Between Phytoplankton and Zooplankton Phytoplanktons are plants while zooplanktons are animals this is the main difference between them. The main kinds of organisms in aquatic ecosystems are free-floating very small organisms called plankton strongly swimming organisms called nekton bottom-dwelling organisms called benthos and decomposers such as bacteria. Is bacteria plankton nekton benthos or decomposers? They can swim in calm water but it is difficult to imagine their being able to swim against currents so I wouldn’t consider them nekton. … Seahorses’ bodies aren’t very good at either kind of motion. As you probably already know seahorses are strange-looking fish. … The only arthropod nekton are decapods including shrimps crabs and lobsters. Nekton the assemblage of pelagic animals that swim freely independent of water motion or wind. Unlike the planktons and benthos nekton can propel themselves either by swimming or other means. Unlike nekton and planktons benthos linked to the ocean floor. What is the difference between Nekton Plankton and Benthos? Nekton live throughout the water column whereas plankton live closer to the water surface.
