Question

A lake has an input of 1 g P m-2 yr-1. Assuming that all the P is used to create algal biomass which is 50% C by weight and has a Redfield molar ratio of 106:16:1 (C:N:P),
a) how much biomass (dry weight m-2 yr-1) could be supported in this lake?
b) how much N (g m-2 yr-1) is also required to support this amount of algal biomass? A lake has an input of 1 g P m-2 yr-1. Assuming that all the P is used to create algal biomass which is 50% C by weight and has a Redfield molar ratio of 106:16:1 (C:N:P),
