A process by which carbon is cycled between the atmosphere, land,water,& organisms.
What is the carbon cycle
100
The percentage of the atmosphere made of nitrogen gas.
What is 78%?
100
Rain, snow, sleet, and hail are all examples of this
What is precipitation?
100
Burning fossil fuels releases this chemical into the atmosphere
What is carbon dioxide?
100
the process of burning materials
What is combustion?
200
The largest reservoir of carbon on earth
What is the ocean?
200
organisms require nitrogen to make this.
What are proteins?
200
the changing of water to water vapor that enters the atmosphere.
What is evaporation?
200
the majority of the Earth's fresh water is frozen in these rapidly disappearing structures
What are glaciers?
200
the process of an organism using a resource in the environment
What is uptake?
300
plants take in carbon dioxide from the atmosphere and create carbohydrates
What is Photosynthesis?
300
Transforms nitrogen into compounds that other organisms can use.
What is nitrogen-fixing bacteria?
300
What is the ultimate driving force for the water cycle?
What is the sun?
300
Global warming or global climate change is primarily caused by this
What is increasing carbon dioxide levels in the atmosphere?
300
bacteria that take the nitrogen in the waste of organisms and convert it back to nitrogen gas in the atmosphere
What are denitrifying bacteria?
400
Animals take in carbohydrates and release carbon dioxide into the atmosphere
What is cellular respiration?
400
takes in nitrogen from the soil to use in biological molecules
What is a producer?
400
the loss of water from plants to the atmosphere though openings called stomata.
What is transpiration?
400
Increased temperatures from global warming result in an increase in this part of the water cycle
What is precipitation?
400
the formation of liquid water from water vapor (i.e. clouds).
What is condensation?
500
the breakdown of dead materials and organisms that recycles nutrients into the soil.
What is decomposition?
500
An organism that gains its necessary nitrogen from producers.
What is a consumer?
500
precipitation falling on the ground seeps into pores that take the water to the groundwater through this process
What is percolation?
500
fertilizer runoff can cause a massive increase in algae and microorganisms in water sources that ultimately kills other organisms. This happens because the fertilizer contains a large amount of this chemical.
What is nitrogen?
500
the unintentional release of harmful substances into the air, soil, or water
