This site not only offers a vast amount of pre-created WebQuests, but it also allows you to create your own in a pre-designed format that is easy to use.
Students walk through the webquest and watch videos on different biomes. Students need to identify the organisms that would be at each level (producers, primary consumers, secondary consumers, tertiary consumers, decomposers). Students will need to create an expository essay about ONE biome and describe the relationships between the organisms within that biome. Students also need to create 2 organism chains from 2 biomes using FRAMES. There are rubrics to go with this project, too.
