WebAssimilation Producers absorb NH4 or NO3 from the soil through their roots. Abiotic Fixation Nitrogen gas (N2) is converted to solid nitrates (NO3) by lightning or synthetic fertilizer production. Ammonification Decomposers break down organic matter into ammonium (NH4). Nitrification Soil bacteria convert ammonium (NH4) into nitrates … WebDenitrification — the process by which bacteria convert nitrate (NO3–) to nitrogen gas (N2), which is lost to the atmosphere. Denitrifying bacteria use NO3– instead of oxygen in their metabolic processes when the soil atmosphere lacks oxygen. Denitrification occurs in waterlogged soil with ample organic matter to provide energy for bacteria. WebDec 11, 2024 · Fixation. Biologically: Nitrogen gas (N2) diffuses into the soil from the atmosphere, and species of bacteria convert this nitrogen to ammonium ions (NH4+), which can be used by plants. Through lightning: Lightning converts atmospheric nitrogen into ammonia and nitrate (NO3) that enter soil with rainfall. rca ant702f antenna review
