biogeochemical cycle
a diagram that shows how matter is recycled throughout an ecosystem
water cycle
water recycled
-oceans
-ground water
-surface water(lakes, rivers, ice)
-atmosphere
evaportaion
when water transforms froma liquid to a gas
condensation
water transforms from gas to liquid
precipitation
rain or snow
transpiration
when water leaves plants as a gas
carbon cycle
carbon can be cycled between:
organic(Biotic)
glucose and other macromolecules
inorganic(abiotic)
carbon dioxide
photosynthesis equation
carbon dioxide+water=Glucose+Oxogen
druirng photosynthesis
carbon is taken from the atmosphere and converted into sugars
During REspiration
carbon is taken from sugars and released as gas
cellular respiration equation
glicose+oxoen=carbon DIioxide+ water
Fossil fuels(carbon sinks)
oila nd coal, carbon trapped in an organic form
