100

a set of interdependent parts that form a whole

What is a system

100

when the output of a system provides information that is used to regulate that system

What is feedback

100

Four main reservoirs for oxygen

What are the atmosphere, biosphere, lithosphere, and hydrosphere

100

Forms of Carbon found in the atmosphere

What are COand Methane

100

The forms of nitrogen

What are N2 , NH, NO, and NO(nitrogen gas, ammonia, nitrites, and nitrates)

200

individual parts that are related

What are components

200

Climate and speaker systems are examples of this type of feedback

What is positive

200
a location in which atoms of an element are held for long periods of time

What is a reservoir

200

2 sources of energy that drive the carbon cycle

What are solar and internal energy

200

Nitrogen is a critical component to these two molecules that make up our bodies

What are DNA and proteins

300

the process of explaining and understanding components in the context of the whole system of which they are a part

What is systems thinking

300

described as when the output adds to the input and makes it larger, thus increasing the input

What is positive feedback

300

produced by photosynthesis

What is oxygen gas/ O2

300

type of carbon found in the hydrosphere

What are carbon dioxide and carbonate

300

The processes of the nitrogen cycle

What are Nitrogen Fixation, Nitrification, Ammonification, and Denitrification

400

what is/isn't part of the system

What are boundaries

400

described as when feedback causes a disturbance to be decreases, increases stability, makes system self-regulating

What is negative feedback

400

produced by accumulation of oxygen in the atmosphere

What is ozone/O3

400

types of carbon found in the lithosphere

What are coal, fossil fuels, and limestone

400

the two natural processes that create ammonia

What are ammonification and nitrogen fixation

500

behaviors/processes

What is flow

500

Lesson Examples of Negative Feedback

What are body feedback systems and natural pest control

500

This is the structural difference between oxygen gas and ozone

What is O2 vs O3

500

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

500

The use of fertilizer created in the process creates extra nitrogen in soil, which leaches into runoff.

What is the Haber-Bosch process
