Response in English: The nitrogen cycle is the process by which nitrogen is converted between its various forms in the environment. It is a continuous cycle that occurs naturally in the environment and is essential for the survival of all living organisms. Heres an overview of the different stages of the nitrogen cycle:1. Nitrogen fixation: Nitrogen gas N2 makes up about 78 of the Earths atmosphere, but its not easily accessible to most living organisms. Nitrogen-fixing bacteria living in soil and in the roots of legume plants convert nitrogen gas into a more usable form - ammonia NH3, which is then converted into ammonium NH4. This process is known as nitrogen fixation.2. Nitrification: Ammonium is then converted into nitrite NO2- by nitrifying bacteria. Nitrite is then converted into nitrate NO3- by another group of nitrifying bacteria. Nitrate is easy for plants to absorb and is an important nutrient for growth.3. Assimilation: Plants take up nitrate from the soil and use it to make organic compounds like proteins, nucleic acids, and chlorophyll. When animals eat plants, they assimilate the nitrogen in these organic compounds and use it to build their own proteins and other molecules necessary for life.4. Ammonification: When plants and animals die or when animals excrete waste, their nitrogen-containing organic molecules are broken down by decomposers. This releases ammonia and ammonium, which can be re-used by plants or converted back into nitrate by nitrifying bacteria.5. Denitrification: Nitrate can also be converted back into nitrogen gas by denitrifying bacteria, which live in anaerobic environments like waterlogged soil or the bottom of a lake. Nitrogen gas is then released back into the atmosphere, completing the nitrogen cycle.The nitrogen cycle is a delicate balance between these various processes, and human activities like agriculture, industry, and transportation can impact the cycle, leading to problems like nutrient pollution and an excess of certain forms of nitrogen in the environment. . Response in Sesotho: Potoloho ea naetrojene ke mokhoa oo naetrojene e fetoloang lipakeng tsa mefuta ea eona e fapaneng tikolohong. Ke potoloho e tsoelang pele e etsahalang ka tlhaho tikolohong me e bohlokoa bakeng sa ho phela ha lintho tsohle tse phelang. Mona ke kakaretso ea mekhahlelo e fapaneng ea potoloho ea naetrojene: 1. Tokiso ea naetrojene: Khase ea Nitrogen N2 e etsa hoo e ka bang 78 ea sepakapaka sa Lefatše, empa ha e fihlellehe habonolo ke lintho tse ngata tse phelang. Libaktheria tse lokisang naetrojene tse phelang mobung le metsong ea limela tsa linaoa li fetola khase ea naetrojene hore e be sebopeho se sebelisoang haholoanyane - ammonia NH3, ebe e fetoloa ammonium NH4. Mokhoa ona o tsejoa e le nitrogen fixation. 2. Nitrification: Ammonium joale e fetoloa nitrite NO2- ka libaktheria tsa nitrifying. Joale nitrite e fetoloa nitrate NO3- ke sehlopha se seng sa libaktheria tsa nitrifying. Nitrate e bonolo hore limela li monye me ke limatlafatsi tse bohlokoa bakeng sa kholo. 3. Ho Amoha: Limela li nka nitrate mobung ebe li e sebelisa ho etsa metsoako ea lintho tse phelang tse kang liprotheine, li-nucleic acid le chlorophyll. Ha liphoofolo li ja limela, li monya naetrojene e metsoakong ena ea lintho tse phelang me li e sebelisa ho iketsetsa liprotheine le limolekhule tse ling tse hlokahalang bophelong. 4. Ammone: Ha limela le liphoofolo li e-shoa kapa ha liphoofolo li ntša litšila, limolekhule tsa tsona tse nang le naetrojene li aroloa ke lintho tse bolang. Sena se lokolla ammonia le ammonium, tse ka sebelisoang hape ke limela kapa tsa khutlisetsoa ho nitrate ka libaktheria tsa nitrifying. 5. Denitrification: Nitrate e ka boela ea fetoloa khase ea naetrojene ka ho hlakisa libaktheria, tse phelang tikolohong ea anaerobic joalo ka mobu o tletseng metsi kapa tlase ho letša. Joale khase ea naetrojene e khutlisetsoa sepakapakeng, e qetellang potoloho ea naetrojene. Potoloho ea naetrojene ke teka-tekano e bobebe lipakeng tsa litsebetso tsena tse fapaneng, me mesebetsi ea batho joalo ka temo, indasteri le lipalangoang li ka ama potoloho ena, e leng se lebisang mathateng a kang tšilafalo ea limatlafatsi le mefuta e mengata ea naetrojene tikolohong.
