Most plants acquire their nitrogen mainly in the form of
a)NH3(ammonia)
b)N2(nitrogen gas)
c)NO3(nitrate ions)
d)amino acids absorbed from the soil
e)urea

C)
They absorb it in the form of NO3, from the soil. It gets in the soil through nitrogen fixation which is the process that bacteria change N2 in the air to NH3, other nitrogen bacteria change NH3 to NO3 which plants can you. Then there are denitrofying bacteria that take NH3 and change it back to N2.

Most plants absorb N from the soil in the form of NO3 ions in solution.
