Question 26

In this model, what best explains why an energy pyramid narrows as you move from the producers toward the top predators?

  1. Top predators are physically larger, so fewer of them fit in the pyramid
  2. Producers hide most of their energy from consumers
  3. Energy is destroyed as it moves between levels
  4. About ninety percent of the energy is lost at each transfer, mostly as heatCorrect answer
