Stream Exploration Ecosystem Investigators | Understanding Connections Between Water and Land
Did you know that Pennsylvania has more than 86,000 miles of streams, creeks, and rivers? Did you know that's more than any other state (aside from Alaska)?
Now, let's dive a little deeper to learn how you can identify organisms you might find and how they work together as part of the ecosystem.

Stream Food Webs
It's perfectly fine if the model looked tangled and overwhelming at first.
If it did, try taking a second look and see if you can work out what it's telling you. You might start by following one pathway from the bottom of the page towards the top, or vice-versa. Once you've looked around and gotten a sense of it, open this worksheet to explore the food web model more in depth.
