Where is most of the nitrogen on earth found?
Most of the nitrogen on Earth is found in the atmosphere, where it makes up about 78% of the air we breathe. It can also be found in the soil, water bodies, and living organisms as an essential element for life processes.
Why do we need nitrogen and why can't we get it from the air we breathe?
Nitrogen is essential for all living organisms to build proteins and DNA. While the air we breathe is about 79% nitrogen, it is in the form of N2 gas which is relatively inert and cannot be used directly by most organisms. Certain bacteria and plants can convert atmospheric nitrogen into a usable form through a process called nitrogen fixation.
What is the largest storage pool of nitrogen in the biosphere?
The largest storage pool of nitrogen in the biosphere is in the atmosphere, where approximately 78% of the air is composed of nitrogen gas (N2). Nitrogen gas is not readily available for most organisms to use directly, so it must be converted into other forms like ammonia or nitrate by nitrogen-fixing bacteria before it can be utilized by plants and other organisms in the nitrogen cycle.
Although air is full of nitrogen it is not available for organisms to readily use nitrogen is changed into which substance before being used by living things?
Nitrogen is transformed into ammonia through a process called nitrogen fixation before it can be used by living organisms. Certain bacteria are responsible for this conversion, either through mutualistic relationships with plants or through free-living nitrogen-fixing bacteria in the soil.
Where is most nitrogen stored on the biosphere?
The majority of nitrogen in the biosphere is stored in the atmosphere, where it makes up about 78% of the air we breathe. Additionally, nitrogen is also found in soil in various forms, such as organic matter, inorganic compounds, and living organisms.
