Intro: This Lab is designed to measure the rates of Photosynthesis and Cellular Respiration in an Aquatic Ecosystem to calculate Net (Primary) Productivity and Gross Productivity Plants perform both Photosynthesis and Cellular Respiration Photosynthesis requires light o Can vary significantly during the day, and does not occur at night Cellular Respiration does not require light o Remains constant throughout the day, and does occur at night Photosynthesis : + + + 6CO2 6H2O Light Energy C6H12O6 6O2 Cellular Respiration: + + + C6H12O6 6O2 6CO2 6H2O ATP Primary Productivity (Net Productivity) - the rate at which sunlight is stored by plants in the form of organic materials, like sugars Higher Primary Productivity = more energy stored in an ecosystem **Note: Primary Productivity does not include energy consumed by a system’s organisms** Photosynthesis and Cellular Respiration occur simultaneously when ecosystems are exposed to light, because Photosynthesis makes the food, while Cellular Respiration consumes it. Net Productivity - the sum difference between Photosynthesis and Cellular Respiration Photosynthesis Rate – Respiration Rate Gross Productivity - the measurement of the Photosynthesis Rate o Obtained by adding the Net Productivity Rate to the Respiration Rate Net Productivity + Respiration Rate
