Net Secondary Productivity (NSP) refers to the amount of energy that is available to consumers after accounting for the energy lost through respiration. In other words, it is the energy that remains in consumers after they have used some of the energy from their food for metabolic processes.

When consumers intake energy in the form of food, they do not convert all of that energy into biomass; a significant portion is used for respiration, growth, reproduction, and other metabolic activities. The energy that is utilized for respiration is lost as heat, which means it cannot be transferred to the next trophic level. Therefore, NSP reflects the energy that is ultimately available to be passed on to higher trophic levels, allowing for growth and reproduction in those consumers, while also providing a measure of the efficiency of energy transfer within an ecosystem.

Options related to total energy absorbed and energy consumed by decomposers do not accurately describe the concept of NSP and its specific relevance to consumers. Decomposers, while important in nutrient cycling, are not the focus when discussing net secondary productivity in consumers.
