The precambrian time period is segmented into very few parts because: a. the fossil record is scarce b. life did not exist c. cyanobacteria were the only life form d. volcanic activity ruined the fossil record select the best answer from the choices provided a b c d

the correct answer is a

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.

the answer is: reproductively

i think i spelled it wrong lol

anyways hope i
