उत्तर
Primary Productivity can be defined as the rate at which primary producers (Green plants) trap and store solar radiation in form of biomass. This is measured in term of weight (g−2) and in term of energy (Kcal m−2) per year in given time. Primary productivity varies from ecosystem to ecosystem and the ecosystem which possess more producer will be more productive in term of primary productivity. So young forests grow quicker than older. mature forest and are more productive in terms of productivity. The shallow polluted lake and alpins meadow will be less productive because of less number of producers and the high amount of dead matter.
