Want this question answered?
if nitrogen fixation does not take place nitrates will not be taken if nitrates are not there so there is no photosynthesis so it metaboills and if photosynthesis is not there so there is no life thats what nitrogen fixation not allows in nitrogen cycle
Heterocysts
This is known as nitrogen fixation.
Nitrogen-fixating prokaryotes (such as bacteria) present in the roots of legumes and some other plants take N2 from the air and convert it to nitrogen compounds usable by plants. Nitrogen fixing bacteria (diazotrophs).
Yes, producers do take in energy from nitrogen. This occurs due to the specific nitrogen cycle that allows for continuous flow of nitrogen through the biosphere which is a result of nitrogen fixation processes.
Lightning strikes and special bacteria that grow on plant roots.
the stroma
You get it every time you take a breath even though you don't need it to survive.
From the soil by the roots or fixation from the air
From old Leaves.
