In order for most plants to take in nitrogen, what must first happen to atmospheric nitrogen (N2)?A. Wait for bacteria to convert N2 into NH 4+ or NO 3- via denitrification.B. Wait for bacteria to convert N2 into NH 4+ or NO 3- via nitrogen fixation.C. Wait for atmospheric N2 to precipitate from the atmosphere, and for the N2 to undergo sedimentation which causes the N2 to be converted into NH 4+ or NO 3- .D. Nothing. The plants can assimilate atmospheric N2 and convert it into NH 4+ or NO 3- internally without bacterial assistance.
