Ko te huri haere o te hauota (N) i roto anō i te pūnaha hauropi. Arā, ka hurihia e te huakita te hauota o te kōhauhau hei pākawa ota (NO3-) meha. Ka kīia tēnei tukanga ko te kapo hauota. Ko te pākawa ota nei te momo hauota ka mitia e te tipu hei hanga pūmua mōna. Ka kainga e te kararehe te tipu, ā, ka puta i a ia te haukini (NH3). Mā te huakita anō e huri te haukini hei pākawa ota. He huakita atu anō kei roto i te oneone e huri ai i te pākawa ota hei hauota ki te kōhauhau. Ka kīia ēnei, he huakita tuku hauota.
The process of nitrogen passing through the ecosystem. Bacteria change the nitrogen in the atmosphere into a soluble nitrate (NO3-), and this process is called nitrogen fixation. The soluble nitrate is able to be absorbed by plants for manufacturing protein. Plants are eaten by animals which produce ammonia (NH3). The ammonia is converted back into nitrates by bacteria. Another type of bacteria in the soil converts the nitrates in the soil back into atmospheric nitrogen. These are called de-nitrifying bacteria
He aha te wāhi ki te huakita i roto i te hurihanga hauota?
Hoahoatia ngā wāhanga matua o te hurihanga hauota.
Ko te hurihanga hauota tētahi mea nui e ora tonu ai nga rauropi katoa o Papatūānuku.
