Question
Chapter 55, Problem 2TYU
Summary Introduction
Introduction: The total fixation of energy by photosynthesis is referred to as gross primary production (GPP). The proportion which remains after respiration loss is termed Net primary productivity (NPP). It depicts the actual rate of the new biomass, which is present for heterotrophs consumption.
