Question

how much of the energy created by producers is available at the secondary consumer level of an energy pyramid? 90 percent 9 percent 10 percent 1 percent

Explanation:

According to the 10% energy transfer rule in an energy pyramid, when energy moves from one trophic level to the next, approximately 10% of the energy is passed on. Producers are the first trophic level. Primary consumers (herbivores) get about 10% of the producers' energy. Then, secondary consumers (carnivores that eat herbivores) get about 10% of the primary consumers' energy. So, if we start with producers (100% energy), primary consumers get 10%, and secondary consumers get 10% of that 10%, which is \(10\%\times10\% = 1\%\) of the producers' original energy.

Answer:

1 percent
