Hello

 

I was wondering whether anyone could help me. I have to answer the following question. I know that I'm probably missing a really simple calculation but I am struggling.

 

Ecosystem Type- Desert Scrub

Surface Area (106 km 2) 19.80

Mean Plant Biomass (kgC m-2) 0.175

Total Plant Biomass (1012 kgC) 3.47

Mean NPP (kgC m-2 yr-1) 0.032

Total NPP (1012kgC yr-1) ?

 

I need to work out the total NPP

 

 

 

Do you follow how they arrived at the 3.47 number for Total Plant Biomass ...from using Total surface area along with Mean plant biomass?

Could you use the same pattern to find Total NPP?
