Which statement best describes the concept that energy moves through an ecosystem and there must be a larger base than the top to maintain a healthy circle of life?

Which statement best describes the concept that energy moves through an ecosystem and there must be a larger base than the top to maintain a healthy circle of life?

• A. Producers
• B. Primates
• C. Imprinting
• D. Energy pyramid

Answer: (D)

Energy moves through an ecosystem from producers up through consumers, and most of the energy at each step is lost as heat. Because of this loss, a diagram that shows a broad base of producers supporting progressively smaller higher levels—the energy pyramid—best describes how energy flows and why the base must be larger to sustain the top. Producers are the organisms that capture energy (like plants), primates are a group of animals, and imprinting is a behavior related to learning; none of these alone convey the idea of energy flow and the need for a larger base like the energy pyramid does.
