-living things need oxygen, hydrogen, nitrogen.
Nitrogen cycle
-ammonia can be made from fungi
-Nitrogen takes up 78% of air
Phosphorous
-leaf drops, decomposers release them back in to the soil and back into a plant.
-fertilizer main ingredient is phosphorous and nitrogen.

# data[].attributes.body
Nitrogen fixing bacteria turn nitrogen into Ammonia. Lightning can also break bonds. Phosphorus, Lithosphere has lots of phosphorus. Lithotrophs eat rocks. Humans messed up environment

# data[].attributes.body
nitrogen is all around us in the air
amonia can be made by fungi and bacteria
denitrifying bacteria turns back into nitrogen
Phosphorus does not include the atmosphere
decomposed phosphate immediately goes back to plants
main ingredient in fertilizers are nitrogen and phosphorus

# data[].attributes.body
NITRO:Plants can eat nitrogen (nitrates,Amonia)
PHOS: Dead things that decompose in water

# data[].attributes.body
nitrogen cycle: nitrogen fixation, nitrogenous,  nitrofying bacteria,  denitrying bacteria.

Phosphorous cycle: doesn't involve atmosphere, lithosphere,

# data[].attributes.body
DNA requires phosphorus

Plants need Bacteria to split Nitrogen Molecules so they can utilize the Nitrogen.
Other types of Bacteria convert the Nitrogen back into Nitrogen Gas.

Phosphorous is not in the air it is in the ground contained in mostly rocks. Bacteria breaks down this Phosphorous and it can then be used by plants. Then once the plant breaks down the cycle can repeat itself.

Human impact on the Nitrogen cycle has affected the environment and the Biosphere

1: What abundant gas in our atmosphere is widely unavailable for us to use? What makes this gas usable for us to use?

2: What two things can break apart N2 gas into a form that organisms can use?

3: Why are bacteria so important to the nitrogen cycle?

4: Where does the majority of the phosphorus we obtain come from? How do we get it? (Lithosphere)

5: What is the process of Nitrogen Fixation? What is denitrification?

6: Fertilizers are largely composed of what materials? What problems can overuse of fertilizer cause

# data[].attributes.body
- nitrogenous can split nitrogen atoms apart
- bacteria helps split the atoms apart
-  lithosphere hold lots of phosphorous
- phosphorous can survive a hundred thousand years in the cycle

# data[].attributes.body
- animals need carbon oxygen and hydrogen
- the air we mostly breath is nitrogen
- lightning can break apart two nitrogen atoms
Phosphorus cycle
- the lithosphere holds a lot of phosphorus
- a phosphorus atom can live for many years

lightning can break nitrogen bonds
plants use nitrogen to make dna

# data[].attributes.body
Nitrogen makes Amino Acids and DNA
Nitrogen is in the air 78% of atmosphere
Nitrogen Fixation - Bacteria converts Nitrogen to Ammonium to Ammonia
Ammonia can be made by decomposers
Nitrifying bacteria converts Ammonia into Nitrates and Nitrites
Denitrifying Bacteria - Turn Nitrates and Nitrites into Nitrogen and releases it into the atmosphere
Lithosphere contains phosphorous
Decomposed phosphate goes from soil to plant to animal to soil very quickly and constantly
We make things better
Fertilizers mainly contain Nitrogen and Phosphorous
Mustard gas was made from fertilizers or something?

# data[].attributes.body
The air we breathe is mostly nitrogen and the rocks are mostly phosphorus.
Lighting has enough energy to break between nitrogen.
Phosphorus cycle- When something dies it decomposes then  turns into ammonia and the cycle repeats
When something decomposes underground and it's too far down it turns into sedimentation.
Fertilizer is made up of nitrogen and phosphorus.

# data[].attributes.body
nitrogen gas takes up 78% of the air

Phosphorus Cycle
- rocks contain phosphorus
