41. Dmitri thought that the primary production can be broken down into gross and net primary production. 42. As of 2014, the majority land use within the locality was primary production . 43. Net primary production is the rate at which new biomass is generated, mainly due to photosynthesis. 44. This weakens the sunlight, reducing the photosynthesis that nourishes the seagrass and the primary production results. 45. Due to the reservoir s high nutrient levels the water is very conducive to primary production . 46. Dmitri thought that the primary production can be broken down into gross and net primary production . 47. For example, predators eating herbivores indirectly influence the control and regulation of primary production in plants. 48. Note the figures are for primary production . 49. Singapore's Primary Production Department was investigating. 50. This mechanism is called primary production .
