Homework Answers
Gross Primary Production in the ecosystem (GPP) = 17,500 kcal/m2
Energy used for respiration (R) = 8500 kcal/m2
Net Primary Production (NPP) is equal to the difference between Gross Primary Production and Energy used for respiration
NPP = GPP - R
= 17,500 kcal/m2 - 8500 kcal/m2
= 9000 kcal/m2
therefore, Net Primary Production (NPP) in the ecosystem is 9000 kcal/m2

NPP = GPP – R Net primary production = ______________ = GPP – energy used for...
NPP = GPP – R
Net primary production =
______________
= GPP – energy used for cellular respiration
Gross primary production = ________________ production of
primary producers
Respiration = ______________________
Thus NPP is the amount of energy available to primary
consumers = primary production
Explain the different ways in which primary production is
influenced in terrestrial and aquatic ecosystems
Primary production: terrestrial
ecosystems influenced by water, temperature, and
nutrient availability
Evapotranspiration rate measures the amount of
water entering the atmosphere...
