Ecology and Systems Biology: Food Web Game

Today we modeled energy transfer through a food chain.  We worked through a brief slide deck and added the words food chain, matter, and energy to our vocabulary list and began thinking about what happens to matter (grass) eaten by an organism (a cow) that does not become food for the consumer of the cow (us, when we eat a hamburger).  We then modeled energy transfer through a selection of Great Salt Lake organisms present in a food chain.  Using 4 different types of beans, we played the Food Web Game and learned how only 10% of the energy in one level of a food chain is passed along to the next level.  The game took us to the end of the period, so tomorrow we will share group data, calculate class averages, and complete page 2 of the Food Web Game worksheet.
