Nitrogen cycle

Information: 

• The air consists of about 78-80% nitrogen
• Nitrogen is important to all elements of life
• Nitrogen must change its state to be used on Earth
• Our bodies does not use the nitrogen but we are living organisms so we need it like all other things
• We get our nitrogen from food we absorb
• Plants get nitrogen from soil
• Fertilizers are used to add nitrogen to soils 
• Too much nitrogen causes things to grow rapidly and acid rain
• Bacteria is the most important part of the cycle 

Fun facts:

• It is used in many explosives
• About 3% of your body weight is nitrogen

Reflection:

We haven't learned and talked about the nitrogen cycle in class but here are the basics. I've always heard of nitrogen from the periodic table and in earth and environmental science. I was under the impression that Nitrogen was always just a gas but there is a whole cycle behind it. The nitrogen cycle is important because it moves between bacteria, plants and animals that all need the nitrogen. N2 is the nitrogen in the air we breathe in. Relating to photosynthesis though, nitrogen is needed to make chlorophyll in plants, which plants use in photosynthesis to make their food and energy. In conclusion, without the nitrogen cycle thing wouldn't balance properly and we couldn't survive.
