What is Nitrogen Fixation?
What is the process of atmospheric nitrogen changing to usable forms?
Nitrogen oxides from burning fuel and using inorganic fertilizers don’t cause nitrogen in the atmosphere
False
What do humans burn that impact the nitrogen cycle?
What are Fossil fuels?
Name the biggest reservoir for Nitrogen
What is the atmosphere?
Name 3 forms
What is Lightning, Bacteria, and cyanobacteria
Aerobic and anaerobic bacteria are types of decomposers
True
What do humans use to help their plants grow, but can affect the nitrogen cycle?
What is Fertilizer
This step in the Nitrogen cycle returns it as a gas to the atmosphere.
What is denitirification?
Ammonia process
What is nitrogen combines with hydrogen to make ammonia and ammonia ions?
Plowing of soils slows down the nitrogen cycle
False
Fertilizer sinks into the soil and is washed into waterways. What happens to streams and ponds in this situation?
This can cause algal blooms to form which is toxic to many different organisms
This step in the Nitrogen cycle features plants taking in Nitrates.
What is assimilation?
Denitrification process
What is soil bacteria converting Nitrate ions to nitrogen gas
Denitrification is when soil bacteria converts Nitrate ions back to nitrogen gas
True
How does deforestation affect the nitrogen cycle?
There are less plants to decompose which leads to less nitrogen in the atmosphere.
All reservoirs for Nitrogen
What are the atmosphere, living organisms, soils, and oceans?
