How do both biotic an abiotic elements involved in the nitrogen cycle?

Answer 1

Best Answer - Chosen by VotersThe only abiotic element in the nitrogen cycle I know of is lightning. Lightning bind nitrogen and some other stuff to form nitrates. There are certain bacteria, primarily found on the roots of legumes, that also partake in nitrogen fixation. Then there are all the other organisms that utilize this nitrogen and eventually release it back into the cycle.
