Group 2 nitrates decompose to basic oxides, NO₂, and O₂. Be(NO₃)2 decomposes most readily to BeO (basic) due to Be²⁺’s small size and high charge density, which weakens the nitrate lattice.

“Denitrification” for which process converts nitrate to nitrogen gas in the nitrogen cycle. This relationship follows from the ecological mechanism represented by the terms in the item, not merely from an association between their names. Ecosystem processes are constrained by energy conservation and by the cycling of matter. Energy enters mainly through primary production, is lost as metabolic heat at every transfer, and therefore cannot be recycled in the way that carbon, nitrogen, phosphorus, or water can. The remaining alternatives—“Nitrification”, “Ammonification”, “Fixation”—refer to different states, processes, or scales and therefore do not express the same causal relationship. The relevant inference should follow the pathway from resource supply to organismal uptake and then to ecosystem-level flux. Productivity, trophic transfer, decomposition, and nutrient regeneration are connected, but each measures a different part of that pathway. This distinction matters because similar surface patterns can arise through different mechanisms, whereas ecological prediction depends on identifying the mechanism that actually changes rates.
