According to the diagram, what is
responsible for converting ammonia
(nh3) to usable nitrates (no3) and nitrites
(no2)?
the nitrogen cycle

a.) lightning
b.) nitrifying bacteria
c.) nitrogen fixing bacteria
d.) denitrification bacteria

Nitrifying bacteria

Explanation:

This process is called nitrification and is done by nitrifying bacteria. First, ammonia is converted to nitrites by nitrosomonas bacteria and then nitrites are converted to nitrated by nitrobacter bacteria. Both these bacteria are nitrifying bacteria

step 1 ammonium can be absorbed by plants, but some is converted into nitrates which are better for plants to absorb. this is called nitrification. 2. step 2 the deer eats the plants and uses the nitrogen-containing proteins for cell growth. 3. step 3 bacteria in the soil conduct nitrogen fixation to convert nitrogen gas from the atmosphere into ammonium. 4. step 4 some of the nitrates are absorbed back into plants, but denitrification breaks down the nitrates into nitrogen gas released back into the atmosphere. 5. step 5 nitrogen is found in the urine, which gets broken down into ammonium through the process of ammonification. 6. step 6 plants absorb the ammonium and begin assimilation, the process to add the nitrogen to protein.
