Answer 1

To calculate the adjusted amount of energy available to organisms that are one trophic level above producers (such as primary consumers), you would typically focus on the net primary productivity (NPP). NPP represents the amount of energy that is stored as biomass after accounting for the energy used in respiration by producers.

The correct response would be:

**gross primary productivity minus amount of organic material used in respiration**

This calculation reflects how much energy is available after producers have used energy for their own metabolic processes, which is essential for determining the energy available to the next trophic level.
