Assertion: The plant biomass which serves as the food of herbivores and decomposers is said to result from the gross primary productivity.
Reason: Gross primary productivity is the rate at which consumers convert the chemical energy of their food into their own biomass.

The correct option is D If both assertion and reason are false.
Net primary productivity is the available biomass for the consumption of heterotrophs(herbivores and decomposers). So the plant biomass which serves as the food of herbivores and decomposers is said to result from the gross primary productivity. The assertion is wrong.
Gross primary productivity of an ecosystem is the rate of production of organic matter during photosynthesis.
Secondary primary productivity is the rate at which consumers convert the chemical energy of their food into their own biomass.
So both assertion and reason are false.
