cc nitrogen and phosphorus worksheet
1: What percent of nitrogen and phosphorus are in an animal’s body?
3% nitrogen and 1% phosphorus.
2: What do we need Nitrogen to make?
We need nitrogen, mainly, AMINO ACIDS.
3: What do we need Phosphorus to make?
We need phosphorus to make DNA and RNA.
The Nitrogen Cycle
4: What percentage of the atmosphere is Nitrogen? What form is atmospheric Nitrogen in?
Nitrogen is 78% of our atmosphere.
5: What is the chemical formula for Nitrate? N2 Nitrite? N3
Ammonium? NH4
6: What is Nitrogen Fixation?
when we try to split atmospheric nitrogen to ammonium.
7: What are Nitrogen Fixing Bacteria?
Bacteria that convert atmospheric nitrogen to ammonia using nitrogenase
8: What plants are in the Legumes Family? What does it mean that they form a symbiotic relationship?
Kudzu, soy, lentils. They let the bacteria stick to their roots, and the bacteria give them ammonium.
9: What form of Nitrogen is usable by plants? What enzyme makes it useful?
ammonium. Notrogenase.
10: What does Nitrifying bacteria do?
It makes it into a form that plants and animals can use.
11: What other things can break Nitrogen molecules apart?
LIGHTNING and synthetic fertilizers.
12: What is De-nitrifying bacteria? Which enzyme does this?
It Metabolizes and use nitrate reductase.
The Phosphorus Cycle
13: What is special about the Phosphorus Cycle?
it is not in the atmosphere at all.
14: What is the Lithosphere? What special type of rock is rich in Phosphorus?
The crust, former sea floor.
15: What is a lithotroph?
Bacteria that eats rocks in the lithosphere.
16: How do Phosphates end up in the water? In the Soil?
They end up in the water by erosion and dissolve into the water.
17: A single Phosphorus atom can get trapped in a cycle for how long?
It can get trapped in the cycle for at least 100 thousand years.

19: What are the main ingredients in fertilizers?
nitrogen and phosphates
20: Why is too much of Nitrogen and Phosphorus bad for the environment?
Too much nitrogen and phosphorus is bad for the environment
3% nitrogen and 1% phosphorus.
