Homework Answers
a is the correct answer because gross primary productivity is total amount of productivity by autotrophic organisms.After using for respiration ,remaining productivity is called net primary productivity.
Add Answer to:
Gross Primary Productivity (GPP) is equal to: a. Respiration + NPP b. The component of energy...
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...

You want to know gross primary production (GPP) of a grassland. You measured both above and belowground net primary production and estimated plant respiration. If you underestimated the true plant respiration, what would this mean for your estimate of GPP? A. You would need information about heterotrophic respiration before you could answer. B. The estimated GPP would be lower than the real GPP C. The estimated GPP would be higher than the real GPP D. GPP is a constant fraction...
