What is happening when nitrogen in the atmosphere is turned into nitrates?

Nitrogen Fixation.

Step-by- step Explanation:

When the atmospheric nitrogen is converted in to nitrates , the process is termed as Nitrogen fixation.Nitrogen Fixation can be non biological or Biological.Non biological nitrogen fixation involves the formation of nitrates from nitrogen through abiotic means.Non biological nitrogen fixation occurs when lightning occurs and provides sufficient energy to break the triple bond of nitrogen to make it react with the  atmospheric oxygen to form oxides of nitrogen.The oxides of nitrogen combine with water vapour or rain and produce nitric acid that seeps into the soil and forms nitrates.Biological Nitrogen fixation occurs when nitrogen fixing prokaryotic organism called diazotrophs convert atmosphereic nitrogen to nitrates through biosynthetic pathway.

This type of galaxy is an approximately ellipsoidal shape and a smooth, nearly featureless image. they are the largest single star systems, in the universe and are built by the collisions of many smaller galaxies.

Neurotransmitters are messengers responsible for communication between neurons. they are released from synaptic vesicles and are received by receptors.  the communication is referred to as neurotransmission. the following statement is true about neurotransmitters: a. they're stored in synaptic vesicles in the axon.
