Answer 2

The nitrogen cycle is the biogeochemical cycle that describes the transformations of nitrogen and nitrogen-containing compounds in nature.

Answer 3

Nitrogen is converted from a gas in the atmosphere to compounds and molecules in plants and bacteria. Then herbivores(plant eating animals) eat the plants and take in nitrogen. When they urinate or deflocate(doo doo) the nitrogen is converted back into a gas by bacteria. That last sentence before this one is also true with animals that eat the herbivores. Also, when animals die, some nitrogen is left in the soil, while the bacteria turn the rest into gas.

Answer 4

it is just like water cycle. The nitrogen in the environment is constantlyused and the recycled to be used again

Answer 5

this is one cycle...
nitrogen in soil --> Nitrosomonus sp. & Nitrobacter sp. preform fixation or nitrfication on the nitrogen to be absorvable by plants --> thenthe plant use it toe make aminoacides to make protien.. --> plant dies --> nitrogen goes back to earth soil....
this is the cycle I know..maybe there are other cycles!
U may check the names of the bacteria & wich preform wich action(nitrification & fixation)'cause it has been a while cince I last cheked them...hop this helps..

Answer 6

carbon + nitrogen = Co2+ N2 = chemistry = hard = dont know
