Correct option:(1)Gross primary productivity is always more than net primary productivity

●Gross primary productivity is the total amount of biomass produced by producers.

●Net primary productivity is the assimilated biomass by the producers.

●They can be passed on to the next trophic level, after being utilized for respiration and lost as heat.
