Fixation of nitrogen
WebMay 14, 2024 · Animals secure their nitrogen (and all other) compounds from plants (or animals that have fed on plants). Figure 17.2.2.1 Nitrogen cycle. Four processes participate in the cycling of nitrogen through the biosphere: (1) nitrogen fixation, (2) decay, (3) nitrification, and (4) denitrification. Microorganisms play major roles in all four of these. WebNitrogen Fixation. As described earlier, fixation is the process of converting dinitrogen gas to chemically reactive forms — where nitrogen combines with other elements such as oxygen, hydrogen, and carbon. …
