plants can utilize the _____ form of nitrogen.
○ n₂
○ amino
○ thiol
○ nitrate

Explanation:

Plants cannot directly use atmospheric nitrogen ($N_2$) due to its stable triple bond. Amino groups are part of organic molecules (like amino acids) that plants can absorb but are not the primary inorganic form. Thiol groups contain sulfur, not nitrogen. Nitrate ($NO_3^-$) is a key inorganic nitrogen form that plants take up from soil via roots and assimilate into organic compounds.

Answer:

nitrate
