Biome productivity
WebJun 26, 2012 · Numerous experiments have found that biodiversity influences the primary productivity of ecosystems and other aspects of ecosystem functioning (1 –6).It also is well established experimentally that productivity of many terrestrial ecosystems depends on the availability of limiting resources, such as soil nitrogen, water, and CO 2, on … In ecology, the term productivity refers to the rate of generation of biomass in an ecosystem, usually expressed in units of mass per volume (unit surface) per unit of time, such as grams per square metre per day (g m d ). The unit of mass can relate to dry matter or to the mass of generated carbon. The productivity of autotrophs, such as plants, is called primary productivity, while the productivity of heterotrophs, such as animals, is called secondary productivity.
