Educator Resources for Close-Knit Neighbors

A jar of pond mud may just look like muck, but it’s actually a complex community of different organisms. Near the top, algae grow and make oxygen from the light. Near the bottom, bacteria feed on sulfur compounds. In between, different communities live wherever is best for them: eating chemicals produced by the things around them, and avoiding chemicals that poison them. In this game, you can create your own ecosystem by rearranging the different communities in our jar. Hover your mouse over different types of bacteria to learn where they would prefer to live in your ecosystem jar.
