The next level after the producer would receive 100 units of energy.
Explanation:
The amount of energy that passes on to the next level is only 10%.
If the producers start with 1000 units, only 10% passes on. The next trophic level would have 100 units, the next after that would have 10, and so on. Only 10% of the energy is passed on into the next level.
