Question
Chapter 53, Problem 8TYU
Summary Introduction
To review:
The reason for a pound of tofu (bean curd) to be more energy efficient than a pound of hamburger.
Introduction:
As per the 10% rule of energy efficacy, only 10% of energy gets transferred from the previous trophic level to the next one in the energy pyramid. The producers, usually green plants, occupy the first trophic level in the grazing food chain. The consumers (animals) occupy the proceeding trophic levels.
