  rdf:value "Medida del ritmo al que nueva materia orgánica se forma y acumula mediante la actividad de la fotosíntesis y la quimiosíntesis de los organismos productores, especialmente de las plantas verdes. El ritmo de la producción primaria se calcula midiendo la cantidad de oxígeno liberado (método del oxígeno) o la cantidad de carbono asimilado por la planta (método del carbono)."@es, "A measure of the rate at which new organic matter is formed and accumulated through photosynthesis and chemosynthesis activity of producer organisms (chiefly, green plants). The rate of primary production is estimated by measuring the amount of oxygen released (oxygen method) or the amount of carbon assimilated by the plant (carbon method)."@en ;
