Owl Pellet and Energy Pyramid Recap

Today we recapped the owl pellet lab and made connections with what we saw and how energy moves through an ecosystem.  We emphasized that no energy transformation can be 100% complete because much of what an organism eats is used to keep the organism alive.  What isn't used for growth, reproduction, daily activities etc., can also be lost as heat.
