Crash Course: Nitrogen and Phosphorus Cycle Guided Viewing Worksheet
1: What percent of nitrogen and phosphorus are in an animal’s body?
The animal's body are made of 3% of nitrogen and 1% of Phosphorus.
2: What do we need Nitrogen to make?
We need nitrogen to make proteins in our muscles, blood, deoxyribonucleic acid, skin, hair and nails.
3: What do we need Phosphorus to make?
We need Phosphorus because it's part of our DNA and RNA ,also is the "P" in PTA. Also we need it in order that nitrogen works. Water and rocks are good sources of Phosphorus.
The Nitrogen Cycle
4: What percentage of the atmosphere is Nitrogen? What form is atmospheric Nitrogen in?
78% percent of the atmosphere is made of Nitrogen. Nitrogen is in a form of nitrates NO3 and nitriteNO2.
5: What is the chemical formula for Nitrate? __NO3____ Nitrite? __NO2____
Ammonium? ___NH4+___
6: What is Nitrogen Fixation?
Nitrogen fixation is the process of nitrogen gas from the air being turned into a compound in the soil by bacteria that live in the root nodules of certain plants (legumes).
7: What are Nitrogen Fixing Bacteria?
Nitrogen fixing bacteria refers to any bacteria that combine nitrogen with oxygen or hydrogen to create compounds that are usable by plants (for instance ammonia, nitrates). This bacteria that fixes nitrogen is called diazotroph.
8: What plants are in the Legumes Family? What does it mean that they form a symbiotic
relationship?
Symbiotic relationships are obligate, meaning that both symbionts entirely depend on each other for survival.
Plants include peanuts, like the picture I have above, beans, and other types of plants. This is a very broad definition of the Legumes Family.
9: What form of Nitrogen is usable by plants? What enzyme makes it useful?
Plants prefer to use NO2 or how we call them "Nitrites". Nitrogenase is an enzyme that makes the nitrogen molecules become more useful.
10: What does Nitrifying bacteria do?
Nitrifying bacteria refers to chemoautotrophic or chemolithotrophs depending on the genera (Nitrosomonas, Nitrosococcus, Nitrobacter, Nitrococcus) bacteria that grow by consuming inorganic nitrogen compounds. Many of these species have complex internal membrane systems that are the location for key enzymes in nitrification.
11: What other things can break Nitrogen molecules apart? lightening has enough energy that can break nitrogen molecules apart. An humans have developed machines that can break synthetic nitrogen molecules apart.
12: What is Denitrifying bacteria? Which enzyme does this?
Denitrifying bacteria is encharged to metabolize nitrogen oxides and release them again intro nitrogen gas by the Nitrate Reductase enzyme.
The animal's body are made of 3% of nitrogen and 1% of Phosphorus.

The Phosphorus Cycle
13: What is special about the Phosphorus Cycle?
Phosphorus enters the environment from rocks or deposits laid down on the earth many years ago.The phosphate rock is commercially available form is called apatite.Phosphate is incorporated into many molecules essential for life such as ATP, adenosine triphosphate, which is important in the storage and use of energy.It is also in the backbone of DNA and RNA which is involved with coding for genetics.
14: What is the Lithosphere? What special type of rock is rich in Phosphorus?
It is the rigid outermost shell of a rocky planet.Oceanic lithosphere consists mainly of mafic(rich in magnesium and iron) crust and
ultramafic(over 90% mafic) mantle and is denser than continental lithosphere.
15: What is a lithotroph?
Lithotrop is a type of the rock eating bacteria .
16: How do Phosphates end up in the water? In the Soil?
They end up in the water by when some or these rocks are exposed they eroded into the soil , and then they dissolve into the water.
17: A single Phosphorus atom can get trapped in a cycle for how long?
It can get trapped in a cycle for it can go for a long time. It can be trapped into for 100,000 of years.

19: What are the main ingredients in fertilizers?
The main ingredients in fertilizers are nitrogen and phosphorus.
20: Why is too much of Nitrogen and Phosphorus bad for the environment? Too much of Nitrogen and Phosphorus is bad for the environment because it carries a lot of nutrients that instead of giving benefits to certain ecosystems or living organisms , it descontrol the balance in which they usuallly are use to
