Solution
The correct option is C T F F T
Statements A & D are correct
Net primary productivity = gross primary productivity – respiration loss.
Net primary productivity is the available biomass for the consumption to heterotrophs (herbiviores and decomposers).
Rate of biomass production is called productivity.
Statements A & D are correct
