The first process of the nitrogen cycle isnitrogen fixation. This is the process of converting atmospheric nitrogen into usable compounds like ammonia, nitrates, nitrites, etc. This is done via several activities. The energy generated during lightning causes oxygen and nitrogen to combine to form ni...

The nitrogen cycle is the system by which nitrogen is converted into different chemical forms, some usable to humans and animals and some not, as it circulates among the atmosphere, the land and the oceans. Encyclopaedia Britannica/Getty Images/HowStuffWorks Living things require nitrogen for ...
From this it has been inferred that the standard thinking about how nature deals with nitrogen in soils and waters needs to be re-evaluated and that the conventional wisdom of how nitrogen is absorbed and released by plants must be wrong. We disagree, however, on the grounds that there are...
Nitrogen is an odorless, tasteless, colorless nonmetallic chemical element which appears in great abundance in the Earth's atmosphere. It also appears in a number of other compounds, and is a vital component of life on Earth for many organisms. In addition to inhaling nitrogen with every breath...
Another cycle is phosphorus nutrient cycle. Phosphates are mostly found in rocks and slowly they dissolve and enter into the water systems, such as lakes or rivers. Eventually they will get into animal and plant life and than back into the earth. ...

MALE STUDENT: What about … well, you said that the nitrogen cycle is also an important nutrient cycle.And there’s a lot of nitrogen in the atmosphere, so I was wondering: Is there a lot of phosphorus in the atmosphere too? FEMALE PROFESSOR: Good question, George.You’re right to gues...
Marine nitrogen fixation: what's the fuss? Biological nitrogen fixation is a much more important process in the nitrogen cycle of the oceans than previously thought. Further, nitrogen fixation may h... DG Capone - 《Current Opinion in Microbiology》 被引量: 295发表: 2001年 If we are all cu...
