Document Summary
Lindeman grouped organisms in a lake into categories based primarily on how they obtained their energy: first in area of ecosystem science, term ecosystem first coined by a. g. tansley to refer to all components of an ecological system. Npp can be estimated by number of methods: measuring npp for ecosystem is importance because changes in primary productivity can be symptomatic of stresses. Co2 uptake: coupled with estimates of efficiency of light absorption to estimate photosynthetic, remote sensing of light reflectance from earth"s surface and atmosphere can be done at large spatial scales using satellites. Nee may potentially decrease: carbon sinks: greater gpp than carbon loss due to respiration, correlations of npp with climate suggest that npp is directly linked to water availability and temperature, particularly obvious in deserts. In lowland tropical rainforests, npp often limited by supply of phosphorus, calcium and potassium: montane tropical ecosystems, most temperate and arctic ecosystems are limited by supply of nitrogen and sometimes phosphorus.
