What is Nitrogen Fixation?

What is the process of atmospheric nitrogen changing to usable forms?

100

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?

100

Name the biggest reservoir for Nitrogen

What is the atmosphere?

200

Name 3 forms

What is Lightning, Bacteria, and cyanobacteria

200

Aerobic and anaerobic bacteria are types of decomposers

True

200

What do humans use to help their plants grow, but can affect the nitrogen cycle?

What is Fertilizer

200

This step in the Nitrogen cycle returns it as a gas to the atmosphere.

What is denitirification?

300

Ammonia process

What is nitrogen combines with hydrogen to make ammonia and ammonia ions?

300

Plowing of soils slows down the nitrogen cycle

False

300

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

300

This step in the Nitrogen cycle features plants taking in Nitrates.

What is assimilation?

400

Denitrification process

What is soil bacteria converting Nitrate ions to nitrogen gas

400

Denitrification is when soil bacteria converts Nitrate ions back to nitrogen gas

True

400

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?
