1. Assume that algae need C, N, and P in the atomic ratios of 106:16:1. a) What is the limiting nutrient in a lake that contains the following concentrations: total C = 15 mg/L, total N = 0.81 mg/L, and total P = 0.12 mg/L. How will reducing P runoff into the lake by 10% affect the amount of algae growth? Explain.

Assume that algae need C, N, and P in the atomic (or molar) ratios 106:16:1. What are the atomic (or molar) ratios in a lake that contains the following concentrations: C = 20 mg L-1, N = 0.80 mg L-1, and P = 0.16 mg L-1? what is the limiting nutrient? Assume that 1/2 of the phosphorus originates from the use of phosphate detergents. Will banning the use of those detergents slow down eutrophication? Why or why not?
