100 4 How many steps are there in the nitrogen cycle?	100 Adding Pesticide/ fertilizers Creating synthetic chemicals burning fossil fuels Name 3 human impacts on the nitrogen cycle	100 From the ammonia/ ammonium formed by the bacterias How do plants gain nitrogen?
200 Nitrogen Fixation, Nitrification, Assimilation, and Denitrification What are the 4 steps of the nitrogen cycle?	200 The process of nitrogen being released from ammonia or ammonium What is denitrification?	200 What organisms break apart the nitrogen diatomNitrifiers/ Nitrating bacteria What organisms break apart the nitrogen?
300 What is nitrification?The process of nitrogen joining hydrogen/oxygen molecules What is nitrification?	300 Nitrous oxide form from the combustion of fossil fuel forms a greenhouse gas trap Due to the harmful gas trap a hole is being formed in the ozone layer The process of making synthetic chemicals containing nitrogen are released into the stratosphere, where the ozone layer is located How is the ozone layer depletion related to the nitrogen cycle?	300 Educate people about our negative and positive impacts Reduce the amount of synthetic fertilizers and pesticides used while gardening Avoid wastage added to water bodies Burn fewer fossil fuels by using renewable energy Recycle, Reuse and be limited with the garbage you produce What can be done to balance the nitrogen cycle?
