How can we gather evidence that the energy in animals' food was once from the sun? Students engaged in several activities where we gathered evidence for this. First, we used packing peanuts to represent the sun's energy. We passed the packing peanuts to a producer, who was able to use some of the energy to make its own food. Some of the packing peanuts fell to the floor, representing the energy going to other organisms or places that can absorb the sun's rays.
From the producer, we passed the energy on to a consumer, who used the energy to go about his daily activities, like hunting, breathing, sleeping, and maintaining his body temperature. Regardless of the animal or the ecosystem he called home, students were able to trace the energy each organism used back to the sun.
