decomposition
What are Geochemical Processes?

How is Nitrogen used?
To build proteins
Nitrogen gas makes up?
78% of Earth’s atmosphere
What things are found in wasted produced by organisms?
Ammonia(NH3)
Nitrite and Nirate ions
What does bacteria convert?
Converts nitrogen gas to ammonia into Nirate and nitrites
Decomposers do what with nitrogen?
They return nitrogen to soil as ammonia
What are Nutrients?
The chemical substance that an organism needs to survive
What are Biotic Factors?
