Use the hypothetical examples below to help you. corn → human corn → cow → human 1. In the corn → human food chain, how does the amount of energy in the corn compare with the amount of energy consumed by the human beings? 2. In the corn → cow → human food chain, how does the amount of energy in the corn compare with the amount of energy consumed by the humans? 3. Do you think it is more efficient for humans to feed on corn or on beef? Hypothetical Examples 1. Corn has 1000 kcal/kg of energy. The amount of energy that a human will receive is 100kcal/kg. 2. We know that the energy content of corn is 1,000kcal/kg. The cow that feeds upon the corn will receive 10 percent of to energy in the corn, which is 100kcal/kg energy.
