Nitrogen Cycle Flashcards
What 3 places are Nitrogen found?
Atmosphere
Deoxynbonuclei acid (DNA)
Protein
Where can nitrogen go and why?
Can go in the ground due to nitrogen fixation (nitrogen fixing bacteria)
Where can nitrogen be stored?
In plants and living organisms
Where in plants can nitrogen be stored?
Roots –> nitrogen fixing bacteria
Where is nitrogen stored in animals?
DNA and Protein
Once Nitrogen goes into the ground what will they become
Ammonium ions
What do ammonium ions become and what process occurs
They will become nitrates due to nitrification - done by nitrifying bacteria
What are nitrates absorbed by and what process will occur?
Absorbed by plants via active transport
What process occurs to get nitrates to become Nitrogen in the air?
Denitrification - performed by denitrifying bacteria
What will plants sometimes have to absorb nitrates, give 2 examples of plants?
Lagooms (beans or pea plants)
How is nitrogen used in plants?
Used to make proteins
Growth and Repair
Why would a farmer plants Lagooms then cultivate them and plant cereal crops?
Nitrates will be absorbed into the ground, meaning they would be used by the cereal crops to create proteins for growth and repair
