Nitrogen Cycle

Question 1

what is the nitrogen cycle

Answer 1

The circulation and reutilization of nitrogen in both inorganic and organic phases

Question 2

4 main processes (I FORGOT ASSIMILATION)

Answer 2

Fixation, Ammonification, Nitrification, and Denitrification

Question 3

whats a symbiotic relationship

Answer 3

living in, or being a close physical association (as in mutualism or commensalism) between two or more dissimilar organisms.

Question 4

whats fixation?

Answer 4

Nitrogen fixing bacteria convert nitrogen into the soil to ammonia which can be taken up by some plants.

Question 5

whats Ammonification

Answer 5

Decomposers convert organic waste into ammonia.

Question 6

whats nitrificaiton

Answer 6

Ammonium converted into nitrate and nitrite (NO2-) through work of nitrifying bacteria.

Question 7

Denitrification?

Answer 7

is the final aspect of the nitrogen cycle. This process is performed by a variety of microscopic bacteria, fungi, and other organisms. Nitrates in the soil are broken down by these organisms, and nitrogen is released into the atmosphere.

Question 8

summary basically

Answer 8

-Nitrogen enters the air (denitrification)
-bacteria fixes nitrogen into organic compounds that plants can absorb
-plants obtain nitrogen
-Herbivores consume nitrogen when eating plants
-decomposers like bacteria and fungi convert ammonia from animal poop and dead animals and plants into ammonium ions
-bacteria convert these ions into nitrites, then nitrates, which plants can take up or leach through the ground
-some bacteria convert nitrates into nitrogen gas (denitrification) and restart the cycle.
