Using the 10% rule, how many Joules of energy should be available at the secondary and tertiary consumer levels?
According to the 10% rule, only 10% of the energy from one trophic level is transferred to the next trophic level. Therefore, at the secondary consumer level, only 10% of the energy available at the primary consumer level is transferred, and at the tertiary consumer level, only 10% of the energy available at the secondary consumer level is transferred.
So, if there are X Joules of energy available at the primary consumer level, the secondary consumer level would have 10% of X Joules (0.1*X Joules), and the tertiary consumer level would have 10% of the energy at the secondary consumer level (0.1*0.1*X Jules or 0.01*X Joules).
