Do only group 1. You will need formulas, data sheet,
and question to complete all. This is about primary production in
aquatic system in marine botany.
Below are the formulas you need to do the calculations Net photosynthetic rate (NPR) LB Final DO-LB Initial Do/time Respiration rate (RR) = DB Initial DO-DB Final DO/time Gross Photosynthetic Rate (GPR) NPR+RR The units for “Seawater Only” bottles are “mg O2/L of water/hr” while units for the seaweed or seagrass bottles are “mg O2/g of tissue/hr” Gross Biomass Productivity (GBP) (0.375xGPR)/1.2. Units for GBP are mg C/g/hr or L/hr.
