MicroBio Chapter 11 Flashcards
The process of conversion of substrate to protoplasmic carbon
Assimilation
Percentage of nitrogen in atmosphere
78%
Atmospheric nitrogen must be fixed n a usable form to be taken by plants. Azetobacter does the fixation
Nitrogen Fixation
The conversion f ammonia to nitrate is performed by soil living bateria
Nitrification
Plant take nitrogen from soil by absorptiom
ASSIMILATION
When a plant dies bacteria convert the organic N2 back to ammonium
Ammonification
Is the reduction of nitrates into inert N2 gas and completes th N2 cycle
Denitrification
It is the slowest biogeochemical cycle
Phosphorous cylce
True or False
Phosphorous can be found in air as gus commonly
False
Exemplifies the connection between organisms in various ecosystems
Carbon cycle
