nitrate cycle

Question 1

what are the four stages of the nitrate cycle

Answer 1

nitrogen fixation
ammonification
nitrification
dentrification

Question 2

define the nitrogen cycle

Answer 2

circuit of nitrogen in the enviroment

Question 3

what does ammonia become

Answer 3

nitrates

Question 4

what is the process of this called

Answer 4

nitrification

Question 5

how does nitrification occur

Answer 5

by nitrifying bacteria

Question 6

what [process then happens to these nitrates

Answer 6

nitrification agian

Question 7

what does this second nitrification form

Answer 7

nitrates no3-

Question 8

why is this second nitrification done

Answer 8

so it is easier for plants to absorb it

Question 9

what two things happens to these nitrates

Answer 9

absorbtion by plants
denitrification

Question 10

when the nitrates are absorbed by the plants what happnens

Answer 10

plants get eaten by living things, thes produce urine and feases

Question 11

what hppens to this urine and faeces

Answer 11

ammonification

Question 12

what does ammonification turn it into

Answer 12

ammonia

Question 13

what else other thn being taken up by plants happens to the nitrates

Answer 13

goes into the atmosphere

Question 14

what happens to the nitrates to allow its absorption into the atmosphere

Answer 14

denitrification

Question 15

what helps perform denitrification

Answer 15

anaerobic denitrifying bacteria

Question 16

not all nitrate goes into the atmosphere, why?

Answer 16

because it stays in the water logged soil as their is less oxygen their

Question 17

why does it stay in the soil

Answer 17

becuase there is not enough oxygen present

Question 18

what is this then converted to

Answer 18

atmospheric nitrogen

Question 19

what is this potentially absorbed by

Answer 19

noduels on legumes
free living bacteria

Question 20

if not absorbed what occours

Answer 20

nitrogen fixation

Question 21

after nitrogen fixation what does this become

Answer 21

it becomes ammonia
