Why must matter cycle?
Since matter can neither be created nor destroyed, and Earth is a closed system, these essential nutrients must be continuously cycled
List the stages of the water cycle
Precipitation, infiltration, runoff, evaporation, transpiration, condensation
List the stages of the carbon cycle
Photosynthesis, cellular respiration, consumption, decomposition, fossilization, combustion
List the stages of the nitrogen cycle
Nitrogen fixation, consumption, decomposition, ammonification, nitrification, denitrification
Unique feature of water cycle
Driven by the sun
Unique feature of carbon cycle
Fossilization
Unique feature of nitrogen cycle
No step completed without living organisms
Human impact on water cycle
Pollution contaminates water
Non-human impact on water cycle
Organisms release water when breaking down food for energy
Human impact on carbon cycle
Burning fossil fuels causes huge uptick of CO2 in atmosphere
Non-human impact on carbon cycle
Decomposers break down carbon from dead organisms
Human impact on nitrogen cycle
Fertilizers add way too much nitrogen to soil
Non-human impact on nitrogen cycle
Decomposers break down dead matter and return nitrogen to the soil
Vocab: biogeochemical cycle
The movement of a particular form of matter through the living and nonliving parts of an ecosystem
Aquifer
An underground layer of permeable rock that can hold water
Eutrophication
When a body of water becomes overly enriched with nutrients, causing excessive algae growth
