26) In an ecosystem, productivity is defined as the amount of organic matter produced or accumulated per unit area per unit time in that particular ecosystem. Primary production of an ecosystem consists of two components: gross primary productivity and net primary productivity.
Gross primary productivity is defined as the rate at which the given ecosystem captures and stores carbon as a plant biomass per unit of time. Net primary productivity is defined as the amount of carbon uptake after subtracting the plant respiration from the gross primary productivity.
Therefore, net primary productivity is the rate of carbon uptake in a system (option c).

Net primary productivity is highest ? a. temperate forest b. tropic c. desert d. high latitude regions
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...
