What is the role of these bacteria in the nitrogen cycle?

Bacteria are very important in the nitrogen cycle because they are responsible for fixing the inorganic nitrogen that is free in the atmosphere in organic nitrogen, which enters the terrestrial trophic networks and leaves them in the form of nitrogenous wastes that go to ground. Bacteria transform molecular nitrogen into ammonia, a form of nitrogen that can be used by plants.

Other bacteria called nitrifying bacteria transform ammonium into nitrite, and then nitrate

answer: - few nutrients

high pressure

low temperatures

explanation: 1. few nutrients:   open-ocean zone is located way far from the land, which is the main source of the essential nutrients.2. high pressure: pressure increases by 1 atmosphere for every 10 meters increase in depth.3. ample sunlight: a large fraction of the sunlight is reflected back to the atmosphere from the sea surface. 4. varying salinity: below the thermocline, the water is isolated from the atmosphere so the salinity remains stable over the year.5. low temperatures:   the temperature of open-ocean zone ranges from a low of -2°c to an average of 17°c

yes!

explanation:

because it has a type of fat that can make you extremely sick
