Produced water from the ground bodies of primary organic matter is the basis of all food animals in the ocean. It turns out that, as biologists say, the food chain: phytoplankton – zooplankton herbivore> – ". Forms of zooplankton predators -> fish -> marine animals in sunny " grass "of phytoplankton " grazing "herbivorous zooplankton and schools of small fish are a food source for large and small carnivores, ie, feeding on living organisms., creatures that are in turn eaten by predators. The last of the top predators, ie, marine apparently should not cause a special sympathy.  However, many of them truly admire the combination of huge size and perfection of form that allows them to move in a dense and viscous sea water as freely and as fast as doing it while hunting their fellow predators on land.  These handsome giants (close our eyes to their predatory habits), no doubt, include tuna with their perfectly streamlined body, dolphins – dive for flying fish, swordfish – record holder in speed among all the fish and animals (up to 109 km / h 100-meter distance), toothed whale, sperm whale – the champion among the animals on diving (to a depth of 3 km) and a courageous fighter with a giant squid (octopuses). The largest of all carnivores – baleen whales (average length of a blue whale is about 24 m, weight – up to 200 tons for comparison: a weight of 50 elephants! ) And some planktivorous shark food that they serve only small crustaceans and small fish. All these creatures have developed themselves, in addition, such abilities as echolocation (the ability to detect objects at long distances due to capture of the reflected sound signals from them) and extremely delicate sense of smell. This helps them detect their prey at distances of several kilometers!

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.
