I am learning about steady state systems and have a problem which is

really stumping me.

 

The Question Taken from John Hartes "Consider a Spherical Cow" is as

follows:

 

Consider a forest in which the residence time for carbon (ignoring

respiratory pathways) in the living trees is 15 years, in leaves is 1

year, and in woody parts (including roots) is 100 years.

 

(a) What is the ratio of leaf biomass to wood biomass?

 

(b) What fraction of total Net Primary Productivity (NPP) does wood

productivity constitute?

 

Biomass = NPP * Residence Time

 

Any assistance would be greatly appreciated in figuring out the steps

to this problem.
