- The Lazy River Environmental Group organized a major cleanup of the pollution from the old factory in late 2010. Measurements of pollution in river sediments before and after the cleanup were analyzed to determine the effectiveness of the cleanup. Select the Sediment Pollutant Over Time dataset and follow the interactive to graph the data. What statement best describes the results of the clean up?If the N and P content of some algae is as shown in the following table. The third column shows nutrient available in the water. Nutrient Nitrogen Phosphorus (a) (b) mg nutrient/g of algae Available, mg/L 0.62 80 6.9 0.15 What percent reduction in nitrogen is needed to control algal production to 1.0 mg/L? What percent reduction in phosphorus is needed to control algal production to 1.0 mg/L?You are culturing 2 algal species. Species A has a maximum photosynthetic output of 8 mg C mg-1 chl a h-1 and a half saturation constant of 20 µE m-2 s-1. Species B reaches a maximum photosynthetic output of 4 mg C mg-1 chl a h-1 and has half saturation constant of 18 µE m-2 s-1. Which species will be growing faster at a PAR light intensity of 80 µE m-2 s-1? Why?
