A living organism in an ecosystem.
What is a biotic factor?
This is a type of gas that is contained in the atmosphere.
What is oxygen?
Evaporation changes water into this form.
What is water vapor?
The circulation and reutilization of nitrogen in both inorganic and organic phases
What is the nitrogen cycle?
Burning these creates carbon in the atmosphere.
What are fossil fuels?
The process of making sugars and gases from sunlight energy.
What is photosynthesis?
This is the other element cycle that is partnered with the oxygen cycle.
What is the Carbon Cycle?
The process of producing or creating water vapor from plants.
What is transpiration?
The two ways nitrates are formed.
What is nitrifying bacteria and lightning?
How Carbon enters the biotic part of the ecosystem
What is photosynthesis?
Non-living organisms in an ecosystem.

What is decomposition?
When condensed droplets of water clump together around tiny dust particles forming this.
What are clouds?
These convert nitrogen gas into a more reactive form for plants to use
What are nitrogen- fixing bacteria?
These are the plants that take the carbon and fix it in organic compounds.
What are forest plants?
The process by which water on the ground surface enters the soil.
What is Infiltration?
The process that uses oxygen when things rust.
What is oxidation?
The downward movement of water through soil and rock due to gravity.
What is percolation?
These are the 4 main processes in the nitrogen cycle
What is Fixation, Ammonification, Nitrification, and Denitrification?
This process takes place in the cells of primary and secondary consumers.
What is respiration?
