Nitrogen cycle
Siužetinės Linijos Tekstas
- NITROGEN FIXATION- ATMOSPHERIC FIXATION
- DURING LIGHTNING, THE HIGH TEMPERATRUES AND PRESSURES CREATED IN THE AIR CONVERT NITROGEN INTO OXIDES OF NITROGEN. THESE OXIDES DISSOLVE IN WATER TO GIVE NITRIC AND NITROUS ACIDS AND FALL ON LAND ALONG WITH RAIN.
- NITROGEN FIXATION- INDUSTRIAL FIXATION
- NITROGEN IS CONVERTED TO AMMONIA AND OTHER CHEMICAL FERTILIZERS..
- NITROGEN FIXATION- BIOLOGICAL FIXATION
- BACTERIA LIKE RHIZOBIUM AND BLUE-GREEN ALGAE TRANSFORM THE UNUSABLE FORM OF NITROGEN INTO READILY USABLE COMPOUNDS WHICH GETS FIXED IN THE SOIL.
- BLUE - GREEN ALGAE
- PLANTS TAKE UP NITRATES AND NITRITES AND CONVERT THEM INTO AMINO ACIDS WHICH ARE USED TO MAKE PROTEINS. THESE PROTEINS AND OTHER COMPLEX COMPOUNDS ARE CONSUMED BY ANIMALS.
- AMMONIFICATION
- WHEN PLANTS AND ANIMALS DIE, THE NITROGEN PRESENT IN THE ORGANIC MATTER IS RELEASED BACK INTO THE SOIL. THE DECOMPOSERS, BACTERIA OR FUNGI PRESENT IN THE SOIL COVERTS THE ORGANIC MATTER BACK INTO AMMONIUM.
- NITRIFICATION
- IN THIS PROCESS, AMMONIA IS CONVERTED INTO NITRITES AND THEN TO NITRATES BY THE BACTERIA LIKE NITROBACTOR IN THE PRESENCE OF OXYGEN IN THE SOIL.
- DENITRIFICATION
- DENITRIFICATION IS THE PROCESS IN WHICH NITRATE IS CONVERTED INTO GASEOUS NITROGEN. IT IS CARRIED OUT BY THE DENITRIFYING BACTERIA LIKE PSEUDOMONAS IN THE ABSENCE OF OXYGEN.
