Answer:
Primary Productivity can be defind as the
rate at which primary producers (Green plants)traps and store solar radiation
in form of biomass. This is measured in term of weight
(g-2)and
in term of energy per year in given
time.
So, 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 forest grow quicker
than older, mature forest and are more productive in terms of productivity. The
shallow polluted lake andalpins meadow will be less productive because of less
number of producers and high amount of dead matter.
