You asked: How is nitrogen cycled through the ecosystem?

How the nitrogen cycle works step by step?

In general, the nitrogen cycle has five steps:

  1. Nitrogen fixation (N2 to NH3/ NH4+ or NO3-)
  2. Nitrification (NH3 to NO3-)
  3. Assimilation (Incorporation of NH3 and NO3- into biological tissues)
  4. Ammonification (organic nitrogen compounds to NH3)
  5. Denitrification(NO3- to N2)

How does nitrogen cycle through the land and ocean ecosystems?

Bacteria in the ocean take the nitrogen, make it into ammonium, then into nitrate. Now, it is used by primary producers, eaten by consumers, and excreted out. The decomposers can now decompose the waste. The bacteria perform denitrification and release nitrogen into the atmosphere.

How does nitrogen get into plants?

Plants cannot themselves obtain their nitrogen from the air but rely mainly on the supply of combined nitrogen in the form of ammonia, or nitrates, resulting from nitrogen fixation by free-living bacteria in the soil or bacteria living symbiotically in nodules on the roots of legumes.
