Plan your ecosystem to be completely self-sustaining. That means, when your model is complete, you will close the top on the bottle and not reopen it. Include as many of the trophic levels within your ecosystem as you can. At a minimum, include 3 plants and 3 different types of invertebrates. No vertebrates may be used.

As part of your diagram, indicate the trophic levels represented in your model.
