To calculate the adjusted amount of energy that is available to organisms that are one trophic level above producers (i.e., primary consumers), you would consider the energy that is available to them after accounting for the energy used by producers for respiration. This is typically represented by Net Primary Productivity (NPP), which is the gross primary productivity (GPP) minus the energy used in respiration by the producers.

Therefore, the correct response would be:

net primary productivity (NPP) plus the amount of organic material used in respiration.

However, since this phrasing is not exactly an option, please look for similar contexts in your options or clarify the phrasing. Generally, though, the energy available to the next trophic level is derived from NPP, not GPP and respiration directly added together.
