Phytoplankton fische Startseite / Tiere & Haustiere / Phytoplankton fische Auch große Fischschwärme ernähren sich von den Planktonmassen. Phytoplankton. Einzellige Kieselalgen machen den Hauptteil des Phytoplanktons aus. Die Zellen. 1 Sie sind die Grundlage allen Lebens im Meer, denn sie sind Nahrung für Fische, Robben, Wale und viele andere Tiere. Ohne Plankton wären unsere Ozeane. 2 Ohne Phytoplankton gäbe es keine Fische im Meer. Phytoplankton wird u.a. von Kleinkrebsen und Muscheln gefressen, die wiederum von Fischen. 3 Zum Plankton zählen Phytoplankton und Zooplankton. Fische wie der Thunfisch oder die Makrele, aber auch Robben und Meeresschildkröten, ja sogar Pinguine. 4 Phytoplankton are eaten by slightly larger, more mobile, herbivores called zooplankton, which range in size from single-celled organisms to jellyfish. In turn, zooplankton provide food for krill and some small fish. Sudden explosive increases in phytoplankton, called "blooms," occur in the ocean when nutrient and sunlight conditions are just right. 5 Some phytoplankton are more nutritious than others and are strong determinants of fish production, whereas others are harmful and can kill fish or contaminate seafood with potent toxins. One group of phytoplankton, the diatoms, are key sources of essential fatty acids and strong determinants of fish production. 6 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'. 7 Phytoplankton are some of Earth's most critical organisms and so it is vital study and understand them. They generate about half the atmosphere's oxygen, as much per year as all land plants. Phytoplankton also form the base of virtually every ocean food web. In short, they make most other ocean life possible. 8 Phytoplankton, also known as microalgae, are similar to terrestrial plants in that they contain chlorophyll and require sunlight in order to live and grow. Most phytoplankton are buoyant and float in the upper part of the ocean, where sunlight penetrates the water. Phytoplankton also require inorganic nutrients such as nitrates, phosphates, and. 9 Because phytoplankton are so crucial to ocean biology and climate, any change in their productivity could have a significant influence on biodiversity, fisheries and the human food supply, and the pace of global warming. Many models of ocean chemistry and biology predict that as the ocean surface warms in response to increasing atmospheric. zooplankton 10 plankton algen 12
