Primary productivity (4 points maximum) *Primary productivity: rate at which autotrophs convert light energy into stored chemical engery *Increase in oxygen = increase in primary productivity *Rate of carbon compound formation measured indirectly through oxygen production *6CO2 + 6H2O--> C6H12O6 + 6O2 *Gross productivity\GPP = rate at which primary producer synthesizes O2 *Net productivity= GPP- producer respiration b i. Pond water at 25 degrees C vs. pond water at 15 degrees C (4 points max) *prediction: DO at 15 degrees C greater than DO at 25 degrees C *Why: saturation DO concentration at 15 degrees is higher than saturation DO concentration at 25 degrees C *Example *Higher metabolic rate of aquatic orgnanisms at warmer temperature = less available oxygen *Fish die in summer ponds/trout live in cold streams *Drinks at room temperature hold less DO than when cold *Elaboration of the example b ii. pond water placed in the dark for 24 hrs vs. pond water placed in the light for 24 hours (4 points max) * Prediction: DO in light greater than DO in dark *Why: photosynthesis higher so DO higher *photosynthesis is light dependent *light bottle is the NET productivity because both photosynthesis and cellular respiration are occuring * dark bottle uses oxygen and respiration only PTS: 1 |
