1st step in the Oxygen Cycle

Plants give out oxygen during the process of photosynthesis.

100

1st step in the cycle

 Carbon is absorbed by plants for photosynthesis

100

Define Nitrogen fixation

nitrogen gas is converted into inorganic nitrogen compounds

100

Explain the role of microorganisms in Earth's nitrogen cycle.

 To capture atmospheric nitrogen by converting it to ammonia

200

2nd step in O2 Cycle

Animals and other aerobic organisms take in oxygen to respire.

200

2nd step

plants are then consumed by animals and carbon gets bioaccumulated into their bodies.

200

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.

200

Why is the nitrogen cycle Important.

Because nitrogen is an essential nutrient for sustaining life on Earth.

300

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.

300

3rd step

After either plants or animals die carbon is released back into the atmosphere.

300

Define Ammoiafication

when Organic nitrogen into ammonia

300

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.

400

One reason why its important

Gives Oxygen

400

4th step

carbon can be turned into man-made fuels.

400

Define nitrification

 a process carried out by nitrifying bacteria, transforms soil ammonia into nitrates

500
Another reason why it's important

maintain the concentration and level of Oxygen in the atmosphere

500

2 forms of carbon

Diamond and Graphite etc

500

Define denitrification.

the loss or removal of nitrogen or nitrogen compounds
