And Reason are true and Reason is the correct explanation of the Assertion.

Explanation: Secondary productivity refers to the production of biomass by heterotrophic organisms (consumers) in an ecosystem. Unlike primary productivity, which involves the synthesis of organic matter by autotrophic organisms (primary producers) through photosynthesis, secondary productivity does not involve the formation of new organic matter.

The Reason correctly explains this as it states that secondary productivity is derived from the utilization of the food (organic matter) produced by primary producers. In other words, secondary consumers obtain the energy and nutrients they need by consuming primary producers or other consumers. They do not create new organic matter, but rather use the existing organic matter to build their own biomass.
