Question

directions: define the terms in the table below. term 1. ammonification 2. nitrification 3. denitrification 4. assimilation 5. nitrogen fixation 6. lightning fixation definition

Explanation:

1. Ammonification: The process by which organic - nitrogen is converted to ammonia by decomposer organisms.
2. Nitrification: The process by which ammonia is oxidized to nitrites and then to nitrates by nitrifying bacteria.
3. Denitrification: The process by which nitrates are reduced to nitrogen gas, returning it to the atmosphere.
4. Assimilation: The process by which plants and animals incorporate nitrogen - containing compounds into their tissues.
5. Nitrogen fixation: The process of converting atmospheric nitrogen gas into ammonia or other nitrogen - containing compounds, either by lightning, industrial processes, or nitrogen - fixing bacteria.
6. Lightning fixation: A natural process where lightning provides the energy to combine nitrogen and oxygen in the atmosphere, forming nitrogen oxides that can be converted to nitrates and used by plants.
