Oxygen Cycle
1st step in the Oxygen Cycle
Plants give out oxygen during the process of photosynthesis.
1st step in the cycle
Carbon is absorbed by plants for photosynthesis
Define Nitrogen fixation
nitrogen gas is converted into inorganic nitrogen compounds
Explain the role of microorganisms in Earth's nitrogen cycle.
To capture atmospheric nitrogen by converting it to ammonia
2nd step in O2 Cycle
Animals and other aerobic organisms take in oxygen to respire.
2nd step
plants are then consumed by animals and carbon gets bioaccumulated into their bodies.
Define Nitrogen assimilation
Nitrates and ammonia resulting from nitrogen fixation are assimilated into the specific tissue compounds of algae and higher plants. Animals then ingest these algae and plants, converting them into their own body compounds.
Why is the nitrogen cycle Important.
Because nitrogen is an essential nutrient for sustaining life on Earth.
3rd step in the O2 Cycle
living beings release carbon dioxide into the atmosphere during the process of respiration. This carbon dioxide is again used by plants for photosynthesis to produce oxygen.
3rd step
After either plants or animals die carbon is released back into the atmosphere.
Define Ammoiafication
when Organic nitrogen into ammonia
how did the Haber-Bosch process has affected the natural nitrogen cycle.
The process of making synthetic fertilizers for use in agriculture by causing N2 to react with H2.
One reason why its important
Gives Oxygen
4th step
carbon can be turned into man-made fuels.
Define nitrification
a process carried out by nitrifying bacteria, transforms soil ammonia into nitrates
maintain the concentration and level of Oxygen in the atmosphere
2 forms of carbon
Diamond and Graphite etc
Define denitrification.
the loss or removal of nitrogen or nitrogen compounds
