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?

b

is correct hope this   also i learnd this in middle school

i think it is dna, i'm not totally sure but i think it might be.

the potatoes have high sugar concentrations and although these potatoes were different we could seethe effects that their sugar concentrations had in different environments. for example, the potatoes in sample a, were placed in pure water. this created a hypertonic environment and caused the potatoes to draw in water from its surroundings. we saw the opposite happen with the potatoes in sample b when placed in the sodium chloride solution. the potatoes in this case were in a hypotonic solution and therefore lost water to their surroundings.
