Document Summary
All the biomass/energy that primary producers make, minus what they use. Defined as: all the growth and reproduction by the primary consumers. Only a small fraction of npp is consumed by herbivores. Trophic efficiency: only a fraction of production (energy) is transferred from one trophic. 1. a. efficiency from one level to the next. Limit the number of trophic levels in a community. Trophic efficiencies also have important implications for the human population. Our agriculture system could feed many more people if we ate more plants and less meat. Source of almost 20% of world"s greenhouse gases (comparable to. Americans reducing meat consumption by 20% is the equivalent of switching from a standard sedan tot prius. Extremely energy intensive: most energy goes toward producing. You can make a difference by choosing different meats. Fish, chicken and pigs are more efficient than beef. Plants bring water up the stem and onto the leaves --> it.
