where do plants get the nitrogen they need to create amino acids and dna?\na plants get their nitrogen from nitrogen gas (n₂), which moves into leaves through holes called stomata.\nb plants take up nitrates (no₃⁻) from the soil and convert them into ammonia (nh₃).\nc nitrogen - fixing bacteria convert nitrogen gas (n₂) into ammonia (nh₃), and plants take up some of the ammonia (nh₃) through their roots.\nd both b and c are correct.\ne a, b, and c are all correct.

Answer

Brief Explanations:

Plants cannot directly use nitrogen gas ((N_2)) from the air. Nitrogen - fixing bacteria convert (N_2) into ammonia ((NH_3)) (as in option C). Also, plants can take up nitrates ((NO_3^-)) from the soil (option B). Option A is incorrect because plants do not take up (N_2) through stomata for nitrogen - containing biomolecules like amino acids and DNA. Since both B and C are correct statements about how plants get nitrogen for creating amino acids and DNA.

Answer:

D. Both B and C are correct.
