Primary production in desert ecosystems is limited by precipitation, nutrient availability (especially nitrogen), and the species' production potential. Plant biomass provides food for consumers that occupy several trophic levels. The resultant transfer of energy and nutrients is also water-limited as are rates of decomposition and activities of decomposer organisms.
