Systems
a set of interdependent parts that form a whole
What is a system
when the output of a system provides information that is used to regulate that system
What is feedback
Four main reservoirs for oxygen
What are the atmosphere, biosphere, lithosphere, and hydrosphere
Forms of Carbon found in the atmosphere
What are CO2 and Methane
The forms of nitrogen
What are N2 , NH3 , NO2 , and NO3 (nitrogen gas, ammonia, nitrites, and nitrates)
individual parts that are related
What are components
Climate and speaker systems are examples of this type of feedback
What is positive
What is a reservoir
2 sources of energy that drive the carbon cycle
What are solar and internal energy
Nitrogen is a critical component to these two molecules that make up our bodies
What are DNA and proteins
the process of explaining and understanding components in the context of the whole system of which they are a part
What is systems thinking
described as when the output adds to the input and makes it larger, thus increasing the input
What is positive feedback
produced by photosynthesis
What is oxygen gas/ O2
type of carbon found in the hydrosphere
What are carbon dioxide and carbonate
The processes of the nitrogen cycle
What are Nitrogen Fixation, Nitrification, Ammonification, and Denitrification
what is/isn't part of the system
What are boundaries
described as when feedback causes a disturbance to be decreases, increases stability, makes system self-regulating
What is negative feedback
produced by accumulation of oxygen in the atmosphere
What is ozone/O3
types of carbon found in the lithosphere
What are coal, fossil fuels, and limestone
the two natural processes that create ammonia
What are ammonification and nitrogen fixation
behaviors/processes
What is flow
Lesson Examples of Negative Feedback
What are body feedback systems and natural pest control
This is the structural difference between oxygen gas and ozone
What is O2 vs O3
this type of organism contributes to the carbon cycle through it's use of solar energy through carbohydrates made by producers using sunlight
What are decomposers
The use of fertilizer created in the process creates extra nitrogen in soil, which leaches into runoff.
What is the Haber-Bosch process
