Question

Choose the statement which are correctly defining the process of N2 fixation] The sequence in which nitrogen passes from the atmosphere to the soil and organisms, and then is eventually released back into the atmosphere, is called nitrogen cycle. The process by which nitrogen is fixed in soil to get absorbed by the plants as soluble substances are; i) During lighting , the high temperature & pressure created in the environment converts nitrogen into oxides of nitrogen. ii)Few free living bacteria converts nitrogen into nitrates & nitrites. iii) Animal & plant bodies fix nitrogen iv)The leguminous plants can fix nitrogen with the help of rhizobium bacteria present in their root nodules. v) A different types of bacteria converts nitrates & nitrites into free nitrogen vi) When animal & plants die their, bacteria in soil convert the compound of nitrogen into nitrates & nitrites

Answer 1

Answer:

This process is called Nitrogen cycle .

Explanation:

this process bacteria convert nitrogen in the soil and release it back into the atmosphere this process is called​ NITROGEN cycle
