  rdf:value "Diferencia entre la cantidad de carbono orgánico fijado en un ecosistema mediante la fotosíntesis (productividad primaria bruta) y la respiración total del ecosistema. La PNE representa la cantidad total de carbono orgánico que se podría almacenar o perder en el ecosistema. Ya sea mayor o inferior a cero, la PNE determina si un ecosistema es autrófico o heterotrófico."@es, "The difference between the amount of organic carbon fixed in an ecosystem by photosynthesis (gross primary productivity) and total ecosystem respiration. NEP represents the total amount of organic carbon available for storage or loss in the ecosystem. Whether NEP is greater or less than zero determines if an ecosystem is autrophic or heterotrophic."@en ;
