11-5 How does energy flow from one organism to the next?
Aim: How does energy flow from one organism to the next?
OBJECTIVE: Explain and construct an energy pyramid to show how organisms
are related by how they get their food.
Key Term
energy pyramid: way of showing how energy moves through a food chain
Lesson Summary
• Along a food chain, approximately 10 percent of the available energy is transferred to the next level.
• The rest of the energy is used to grow, search for food, and reproduce.
• Some energy is stored and some is lost into the environment as heat.
• An energy pyramid shows how energy moves through a food chain.
