The amount of biomass product per unit area over a time period by plants during photosynthesis is called
The correct option is A Primary production
A.Primary
production – The amount of biomass product per unit area over a time period by
plant during photosynthesis is called Primary production.
B.Net
primary production - s the rate at
which all the plants in an ecosystem produce net useful chemical energy; it is equal to the
difference between the rate at which the plants in an ecosystem produce useful chemical energy
(GPP) and the rate at which they use some of that energy during respiration.
C.Gross
primary production - the amount of
chemical energy as biomass that primary producers
create in a given length of time
D.secondary production - the
generation of biomass of heterotrophic (consumer) organisms in a system. This
is driven by the transfer of organic material between trophic levels, and
represents the quantity of new tissue created through the use of assimilated
food.
So,
the correct option is ‘ Primary production’.
