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
