Question

Quizplus · Accepted Answer

The correct answer is B) 1,000 kcal. This is because of the trophic level energy transfer efficiency, which is roughly 10%. This means that to get 100 kcal of energy from soybeans (which are producers), about 10 times that amount, or 1,000 kcal of soybeans, would need to grow. This accounts for the energy lost in the process of the soybeans converting sunlight into edible plant matter.
