Using the equation NPP = GPP – R, answer the following questions.
1) If the GPP for a patch of forest is 10.675 kg C/ m2-year, and the amount of carbon dioxide LEAVING the ecosystem is 4.343 kg C/ m2-year, what is the NPP?
2) __________________ light is absorbed in top 1m, ___________ light only gets to 100m.
1) To find the NPP, we need to subtract the amount of carbon dioxide leaving the ecosystem (R) from the GPP.
NPP = GPP - R
NPP = 10.675 kg C/ m2-year - 4.343 kg C/ m2-year
NPP = 6.332 kg C/ m2-year
2) The missing information in the question prevents us from answering this part.
