Question
Wastewater with a nitrogen/phosphorus (N/P) ratio of 8 by atoms is being discharged into a lake. The N/P ratio of the algae in the lake is 16 by atoms. Assume that the wastewater is the only significant source of nitrogen and phosphorus for the lake and that either N or P limits algal biomass in the lake. What will happen to the algal biomass in the lake if 2.7 The N in the waste water is increased by a factor 10 a) No change b) Increased by a factor of 2 c) Increased by a factor of 5 d) Increased by a factor of 10
Explanation / Answer
Answer:
As the relation given in the question that N/P ratio of algae is differ by factor 2 of N/P ratio of waste water.( since, N/P of waste water= 8 and the N/P of algae = 16)
Therefore, by increasing the value of 2.7 Nitrogen in waste water by factor 10 will increase the algal biomass by factor of 2.
