In what ways can nitrogen gas be broken down into nutrients for plants

it can be done by oxidation and reduction.

Some nitrogen fixing bacterias are also responsible for converting atmospheric nitrogen into nitrates that plants can use (e.g ribozhium )

bacterias in the soil participate in nitrification as well, oxidizing ammonium ions into nitrates which plants can use.

Explanation:

Oxidation produces nitrate compounds

reduction produces ammoniacal compounds.

for  example, forests have higher evapotranspiration than other ecosystems,  such  as grasslands, because of their deeper roots and greater leaf area. thus forests have a net moistening effect on the atmosphere and become a moisture source for downwind ecosystems.

when you breathe in, or inhale, your diaphragm contracts (tightens) and moves downward. this increases the space in your chest cavity, into which your lungs expand. the intercostal muscles between your ribs also enlarge the chest cavity. they contract to pull your rib cage both upward and outward when you inhale.
