Answer 2

Answer:

nitrogen fixation is a process in which the nitrogen present in the atmosphere is used by the plants .

this happens as:

plants cannot use the nitrogen directly.it needs to be converted into soluble compounds so yhat they can use. it.so for this the leguminious crops or plants have rhizobium bacteria in their root nodules that helps in converting nitrogen to nitrates. in another way by lightning also and when plants and animals die the microbes decompose them by breaking the nutrients into soluble compounds and thus nitrogen in the plnt or animal body is broken down to soluble compounds and help in nitrogen fixation ...

here is the answer
