Detailed explanation-1: -Biomass Production. Net primary production (NPP) is strictly defined as the difference between the energy fixed by autotrophs and their respiration, and it is most commonly equated to increments in biomass per unit of land surface and time.
Detailed explanation-2: -Net primary productivity, or NPP, is gross primary productivity minus the rate of energy loss to metabolism and maintenance. In other words, it’s the rate at which energy is stored as biomass by plants or other primary producers and made available to the consumers in the ecosystem.
Detailed explanation-3: -Primary production is defined as the amount of biomass or organic matter produced per unit area over a time period by plants during photosynthesis.
Detailed explanation-4: -The rate of biomass production in an ecosystem is called productivity. They are of two types, gross primary productivity and net primary productivity.
