A Pyramid of Energy: Name: ____________________________Energy Transfer in an Ecosystem

What You Do: Practice calculating the transfer of energy through an ecosystem.

1. Create a food chain using the following: algae, tadpole, minnow, sun, Blue Heron, alligator.

2. Based on the word parts of PRImary, SECONDary, TERTIary͕�ĂŶĚ�Yh�Zd�ZŶĂƌLJ consumer, what label would youprovide for the�alligator? Explain.

3. If the amount of energy from the sun in the food chain from #1 equals 2500 units, calculate the energy available at eachlevel of the energy pyramid for the producer and each of the consumers that follow. Use the energy pyramid on thefront page to guide you.
