Microbial population in natural water (marine and fresh water)???

1.	Microbial population in natural water (marine and fresh water)???
Answer» Answer: Water covers seven tenths of the Earth's surface and occupies an estimated total volume of 1,386,000,000 cubic kilometers (km3). Of all the water found on Earth, 97% is marine. Maximum of this water is at a temperature of 2 to 3°C and devoid of light; 62% is under high pressure (>100 atm). Microscopic phytoplankton and associated BACTERIA generate a complex food web that can extend over long distances and EXTREME depths. The marine environment looks so vast that it will not be able to be exaggerated by pollution; however, in coastal areas human activities are increasingly disrupting microbial processes and damaging water quality.Nepal Journal of Biotechnology.
