carbon n nitrogen

Question 1

Ammonification

Answer 1

NO3- from leaves gets turned to NH4+/NH3 by decomposers

Question 2

Nitrification

Answer 2

NH4+/NH3 get turned to NO2- by nitrosomonas

Question 3

NO2- –> NO3-

Answer 3

Nitrobacter

Question 4

Denitrification

Answer 4

NO3- gets turned into N2 by pseudomonas

Question 5

N2 + H2

Answer 5

Azotobacter/Rhizobium get turned into NH4+ / NH3

Question 6

NH4+/NH3 and NO3-

Answer 6

Can get taken up by the plant

Question 7

Carbon cycle

Answer 7

CO2 taken in by trees for photosynthesis, Animals eat trees

Animals and trees respire, bring CO2 back to atmosphere

Dead animals die, and get decomposed by decomposers
Decomposers send CO2 back to the atmosphere

Dead animal can turn into fossil fuels, through combustion by humans, CO2 returns to the atmosphere
