Plankton
Plankton are a multitude of living organisms adrift in the currents.Our food, our fuel, and the air we breathe originate in plankton.

Phytoplankton bloom observed in the Barents Sea (North of Norway) in August 2010 by the ocean color sensor MODIS onboard NASA satellite Aqua. Changes in ocean color result from modifications in the phytoplankton composition and concentration. The green colors are likely associated with the presence of diatoms. The shades of light blue result from the occurrence of coccolithophores, phytoplankton organisms that strongly reflect light due to their chalky shells - Source : NASA's Earth Observatory (http:/earthobservatory.nasa.gov)
Diatoms - Life in glass houses
Champions of photosynthesis, these unicellular organisms appeared at the time of dinosaurs.They produce a quarter of the oxygen we breathe.
