If 1000 units of energy are available at the producer level of the energy pyramid, about how many units are available for first-level consumers? Second-level consumers? Third-level consumers?

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.
