rich and diverse flora and fauna of the oceans and seas is classified as genus, species, habitat, etc. The most important quantitative characteristics are concepts such as biomass and biological productivity. Biomass – a total weight of organisms per unit area or volume. The biological productivity that characterizes the reproduction of living organisms in the oceans, which in many respects similar to the more familiar four land "the concept of " performance ". Plankton, along with bacteria is the most Coast population, both in number and biomass. The most important role is played here with very high rates of reproduction of phytoplankton. Annual "crop " of phytoplankton in the thousands Blue Ocean Planet nivah times greater than the total mass of phytoplankton, while the harvest of the earth years of vegetation by increased only 6% of their biomass. But most importantly, the phytoplankton has an amazing ability to create an organic material is exposed to sunlight because of their content in their cells, a special substance – chlorophyll. At the same time as a result of this process is allocated as needed for all life on earth with oxygen. Given the enormous biomass and productivity of phytoplankton, the oceans can be called a big "fabric of life. " Y "factory " instead of oppressing and reeking of smoke emits life-giving oxygen.
