Wer produziert Phytoplankton?
Phytoplankton baut als Primärproduzent mit Hilfe der Photosynthese aus Kohlenstoffdioxid und Nährstoffen seine Körpersubstanz (Biomasse) auf (Primärproduktion).
Was ist mit dem Begriff Plankton gemeint?
Als Plankton bezeichnet man alle Lebewesen im Meer und im Süßwasser, die sich nicht selbst fortbewegen können, sondern sich von der Wasserbewegung treiben lassen. Es gibt pflanzliches und tierisches Plankton. Zum pflanzlichen Plankton sagt man Phytoplankton, das tierische Plankton heißt Zooplankton.
What do phytoplankton do in the ocean?
Phytoplankton are mostly microscopic, single-celled photosynthetic organisms that live suspended in water. Like land plants, they take up carbon dioxide, make carbohydrates using light energy, and release oxygen. They are what is known as primary producers of the ocean—the organisms that form the base of the food chain.
Where does the carbon go when phytoplankton die?
Some of this carbon is carried to the deep ocean when phytoplankton die, and some is transferred to different layers of the ocean as phytoplankton are eaten by other creatures, which themselves reproduce, generate waste, and die. Phytoplankton are responsible for most of the transfer of carbon dioxide from the atmosphere to the ocean.
What is the difference between seaweed and phytoplankton?
Seaweed is a macro-algae while phytoplankton is a micro-algae and a type of plankton. But what is plankton? The plankton definition is marine and freshwater organisms that are too small or weak to swim against the current so they exist in a drifting or wandering state.
What is the role of swirls and filaments in phytoplankton?
In particular, the role of the swirls and filaments (mesoscale features) appear important in maintaining high biodiversity in the ocean. Phytoplankton obtain energy through the process of photosynthesis and must therefore live in the well-lit surface layer (termed the euphotic zone) of an ocean, sea, lake, or other body of water.
