Biological Significance
Why study diatoms? Diatoms constitute approximately 40%
of the phytoplankton in the world, and they therefore make up 20-25%
of the world's net primary productivity. They played a large role
in the development of mariculture and sea farming. Diatoms were
used as food for the larvae of echinoderms, mollusks, and shrimp.
They have also been an indicator of water quality and pollution,
as they are able to uptake and bind both organic and inorganic
substances (pollutants). In addition, diatoms have been the subject
of a great deal of interesting research. Permeability studies and
silicon metabolism studies have been conducted using diatoms. During
the present day, these studies continue as there continues to be
a great deal to learn about the world of diatoms.
