Diatoms food chain
WebMay 4, 2024 · Diatoms are major producers in aquatic environments; that is, they are responsible for as much as 40% of the photosynthesis that occurs in fresh water and in the oceans. They serve as the main base of the food chains in these habitats, supplying calories to heterotrophic protists and small animals. These, in turn, feed larger animals. Webhave repeatedly demonstrated that a diatom-based food chain leads to higher growth rate and better con-dition of fish larvae - which feed on copepods - com-pared to a dinoflagellate-based food chain (St. John & Lund 1996, Hansen 1998). Finally, the only field study that has simultaneously monitored egg hatching suc-
