1: What percent of nitrogen and phosphorus are in an animal’s body? They are 3% nitrogen and 1% Phosphorus.
2: What do we need Nitrogen to make? We need Nitrogen to make amino acids which produce proteins
3: What do we need Phosphorus to make? We need Phosphorus because it's part of our DNA.
4: What percentage of the atmosphere is Nitrogen? What form is atmospheric Nitrogen in? 78%. Nitrogen is in a form of nitrates NO3 and nitrite NO2.
5: What is the chemical formula for Nitrate? ____NO3______ Nitrite? ____NO2_____ Ammonium? NH4
6: What is Nitrogen Fixation? Nitrogen Fixation is when nitrogen molecules breaks apart into nitrates and nitrite and also ammonium, all of this is in order to plants absorb the nutrients of nitrogen.
7: What are Nitrogen Fixing Bacteria? They product of the nitrogen fixation. They are located into soil, water, to be more specific "Legumes".
8: What plants are in the Legumes Family? What does it mean that they form a symbiotic relationship? Legumes family is really huge, they can be peanuts, soybeans, clover, etc. Symbiotic Relationship means that two organisms are equally benefit from each other.
9: What form of Nitrogen is usable by plants? What enzyme makes it useful? NO2. Nitrogenize is an enzyme that makes the nitrogen molecules more useful.
10: What does Nitrifying bacteria do? Nitrifying bacteria is uncharged to take ammonia and convert it into Nitrates NO3- and Nitrites NO2.
11: What other things can break Nitrogen molecules apart? Lightening have 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 uncharged to metabolize nitrogen oxides and release them again intro nitrogen gas by the Nitrate Reeducates enzyme. 13: What is special about the Phosphorus Cycle? Something special about the Phosphorus cycle is that is the only cycle that doesn't involved the atmosphere.
14: What is the Lithosphere? What special type of rock is rich in Phosphorus? The Lithosphere is also know as the Earth's crust . A type of rock that is rich in Phosphorus are the sedimentary rocks that are in the old ocean floor.
15: What is a lithotroph? Lithotroph 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 when some are exposed and 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.
18: Diagram the Phosphorus Cycle below:
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 decontrol their regular balance, which throws them off.
