Use the following chemical formula to represent algae: c106h263o110ni6p (3553 g/mol) (a) calculate the mass ratio of n: p in the algae. (b) suppose 10 mg/l of ammonia nitrogen and 2.5 mg/l of orthophosphate as phosphorus are available in lake water. determine which nutrient is limiting by calculating the potential algae production from these concentrations (c) suppose the n concentration is held constant and the p concentration is dropped to 1 mg/l what is the n: p mass ratio in the water? which nutrient is limiting? (show calculations.) (d) suppose the p concentration is held constant and the n concentration is increased to 20 mg/l what is the n: p mass ratio in the water? which nutrient is limiting? (show calculations.) (e) write out a general rule by which you can decide the limiting nutrient by comparing n: p ratios (f) supposing that the n concentration is 10 mg/l, use the n: p ratio of the algae to determine the concentration at which p becomes limiting. verify this by calculating the potential algae growth using this concentration. answers: (a) 7.23: l; (b) 158.6 mg/l based on n, 286.5 based on p, n limits; (c) 10, 114.6 mg algae based on p, p limits; (d) 8, 317.2 mg algae based on n, p limits; (e) when (n: p)environment> (n: p)algne is the limiting nutrient; otherwise is. () 1.38 mg p, 158.5 mg algae
