Why is it important?

An aquatic classical food web comprises phytoplankton, zooplankton and fish (planktivorous and predatory ones) as predominant elements, which in turn define the linear direction of an energy-flow pathway and nutritional transfer. Phytoplankton provides many valuable phytonutrients and biologically active ingredients, especially fatty acids, amino acids, sterols, organic minerals, enzymes, carotenoids, chlorophyll, trace elements, and vitamins, which are directly available for the first larval/juvenile stages of fish or indirectly (through trophic chains) for the more mature forms.
