Biogeochemical Cylce Flashcards
biogeochemical cycle
process when materials necessary for an organisms survival are throughout the environment
hydro logic cycle (water cycle)
transfers water from the ocean to the atmosphere to continents and back to oceans.
where is fresh water stored
- polar ice caps
- the ground
what % of water is salt water
97%
what % of water is fresh water
2% found in glaciers
sublimation def
evaporation of water
evaporation def
when liquid water turns to water vapor
transpiration
lose of water through the stomata/leaf
what increases evaporation rates?
temperature, sun intensity, wind, plant coverage, and ground moisture
evaporation decreases as…..
humidity increases
percipation def
when water vapor condenses to clouds and falls down in various forms
percolation
action of water as it goes to the ground
surface runoff def
when water flows down rivers or oceans
when does runoff start to decrease
during drought
when does runoff increase
rainy seasons and rapid ice melting
nitrogen cycle
the time when the carbon enters the soil, becomes part of living organisms, and goes back to atmosphere
what makes amino acids
nitrogen, because the body needs proteins
how much of the earths atmosphere is nitrogen
~78%
If a word is capitalized and in italicizes….
it is alive
what makes nitrogen useable
bacteria
what are the usable forms of nitrogen
ammonium and nitrogen ions
what does the body do with the nitrogen it doesn’t use?
its expelled by pee, making it smell
animals wastes and dead organisms nitrogen does what?
it is broken done by bacteria
