WebNitrogen enters the living world from the atmosphere via nitrogen-fixing bacteria. This nitrogen and nitrogenous waste from animals is then processed back into gaseous nitrogen by soil bacteria, which also supply terrestrial food webs with the organic nitrogen they need.

The Nitrogen Cycle. Like oxygen, nitrogen is essential for livings to survive on Earth. Animals and plants need nitrogen to build amino acids in proteins, which are the building blocks of life.
WebJul 2, 2024 · The cycle of nitrogen incorporation in growing plant tissues and nitrogen release by bacteria from decomposing plant tissues is the dominant feature of the nitrogen cycle and occurs very efficiently. Nitrogen can be lost from the system in three main ways. WebIn the nitrogen cycle, nitrogen-fixing bacteria convert atmospheric nitrogen into ammonia (ammonification). The ammonia can then be oxidized to nitrite and nitrate (nitrification). Nitrates can then be assimilated by plants. Soil bacteria convert …
