5056389832	Primary Productivity	gain of new biomass or energy by PRODUCERS per unit area per unit time (photosynthesis)	1
5056391468	Secondary Productivity	the biomass gained by CONSUMERS per unit area per unit time (FEEDING OR ABSORPTION)	2
5056398256	Measuring Primary Prod.	1. Use rate of photosynthesis 2. Rate of increase in DRY biomass	3
5056401099	GPP	NPP=GPP - R NPP: change in O2 R: respiration	4
5056403822	NPP	gain of energy/biomass (per unit area per unit time) remaining AFTER respiratory loss	5
5056428638	NSP	NSP = GSP - R GSP= food eaten-fecal loss	6
5056451084	CO2 in Atmos?	0.039%	7
5056459651	The rate of assimilation of carbon in water depends on the type and quantity of plants within the water. Primary productivity is the measure of this rate of carbon assimilation. As the above equation indicates, the production of oxygen can be used to monitor the primary productivity of an aquatic ecosystem. A measure of oxygen production over time provides a means of calculating the amount of carbon that has been bound in organic compounds during that period of time. Primary productivity can also be measured by determining the rate of carbon dioxide utilization or the rate of formation of organic compounds.		8
5056479642	The difference between the amount of oxygen produced through photosynthesis and that consumed through aerobic respiration is the net productivity.		9
5056480157	The difference in dissolved oxygen over time between the bottles stored in the light and in the dark is a measure of the total amount of oxygen produced by photosynthesis. The total amount of oxygen produced is called the gross productivity.		10

5056485725	CC Aquatic Prod	remove CO2 from water with photosynthesis	12
5056487556	CC P C and D	use aerobic resp to break glucose and make CO2	13
5056488465	CC Decamp.	release CO2 from dead organisms	14
5056490142	CC Largest Storage	Marine Sediments	15
5056490714	CC H.E	1) Adding choke CO2 to atmos by burning fossil fuels 2) Clearing Carbon Absorbing Vegetation Faster than Grown 3) Altering rate of energy flow and cycling of nutrients	16
5056494623	Enhance Greenhouse Effect	CO2 + CH4 (methane) increase greenhouse effect = hotter	17
