Measuring+Productivity

Formulas: Respiration Rate in terms of oxegyn comsumption is equal to the initial concentration of oxygen minus the final concentration of oxygen in the dark sample bottle, divided by the time elapsed. Gross Photosynthetic Productivity of oxygen is equal to the final concentration of oxygen in the light bottle minus the final concentration of oxygen in the dark bottle, divided by the time elapsed. Net Productivity of oxygen is equal to the Pg minus R.

-Producers and primary consumers are largely microscopic plankton suspended in the water. By measureing the rates of oxygen production and of oxygen productivity the respiration can be calculated.

Vocab: Respiration Rate measures the amount of oxygen consumed by the respiration of algae, bacteria, and other pond organisms over a period of time. Gross Photosynthetic Production measures the amount of oxygen produced by photosynthesis. Net Productivity is the amount of energy in the ecosystes after subtratcing the needed amount of oxegyn to survive.

~These are vital to understanding what productivity is over produced.
 * Energy enters the ecosystem through light and is then consumed by the organisms in theparticular pond which later leaves the ecosystem through heat energy.
