Question

Quizplus · Accepted Answer

In a typical ecosystem, energy transfer follows the 10% rule, where only about 10% of energy is transferred from one trophic level to the next. Primary producers (plants) are the first level, primary consumers (herbivores) are the second, and secondary consumers (carnivores like foxes) are the third. Thus, a secondary consumer receives about 1% of the energy fixed by primary producers.
