CARBON CYCLE- MAIN PROCESSES
▸ PHOTOSYNTHESIS
▸ CELLULAR RESPIRATION
▸ DECOMPOSITION
▸ COMBUSTION
p. 1228
CARBON STORAGE
▸ Ocean is a carbon “sink”
▸ CO2 fixed into carbonic acid; allows ocean to absorb more
▸ Stored in limestone sediments in the deep ocean
▸ About 1/2 of the Earth’s amount is there
CARBON CYCLE- GLOBAL WARMING
▸ PO43- = phosphate ion; DNA backbone
▸ A limiting nutrient in most aquatic ecosystems- why?
THE PHOSPHORUS CYCLE
PHOSPHORUS CYCLE- MAIN PROCESSES▸ Weathering
▸ Uptake by plants and consumption
▸ Decomposition
▸ Leeching
▸ Collection in aquatic environments
▸ Geological uplift
p. 1229
CARBON AND WATER CYCLE REVIEW
TEXT
▸ 78% of atmosphere is N2
▸ Nitrogen used in production of proteins and DNA/RNA
NITROGEN CYCLE- MAIN PROCESSES▸ Nitrogen fixation
▸ Ammonification
▸ Nitrification
▸ Assimilation
▸ Denitrification

SUCCESSION
▸ Sequential changes in an environment over time
▸ Ultimate goal: stability
▸ Connection to biodiversity?
▸ Pioneer species
PRIMARY SUCCESSION
▸ No life before; not previously colonized
▸ Begins from rock and glacial movement; volcanic formations. No soil present!
▸ Long-term
▸ Pioneer species?
PRIMARY SUCCESSION
PRIMARY SUCCESSION
SECONDARY SUCCESSION
▸ Area previously colonized
▸ Caused by a disturbance
▸ Short-term
▸ Pioneer species?
