- Give typing answer with explanation and conclusion A biologist is measuring photosynthesis and respiration in a lake. She places a pair of bottles in the lake and measures the initial oxygen concentration to be 9.56 mg O2/L. Twenty-four hours later, she measured the oxygen concentrations in the light and dark bottles: 8.23 mg O2/L in the dark bottle and 10.11 mg O2/L in the light bottle. Calculate the hourly rates of NPP and respiration for this ecosystem. Be sure the units are correct. A) NPP=0.0229 mg O2/L/h, R=0.0554 mgO2/L/h B) NPP=.55 mgO2/L/h, R=1.33 mgO2/L/h C) NPP=-0.0554 mgO2/L/h, R= -0.0229 mgO2/L/h D) NPP=0.0229 mg O2/L, R=0.0554 mgO2/Larrow_forward“Photosynthesis is the single most important process for life on Earth.” Discuss this statement in some detail.arrow_forwardCompare and contrast the calvin cycle and the krebs cycle.arrow_forward
