You may have heard the advice to “eat low on the food chain.” Explain how choosing a soybean-protein “burger” rather than a beef burger for lunch is energy efficient with respect to energy flow and utilization in trophic levels.
What will be an ideal response?
The soy-burger has more available energy than in a beef burger prepared from an animal higher on the food chain if one considers the total amount of sunlight energy initially captured by plants. Each trophic level results in a decreased amount of available energy.
