Ecology Photo

I’m trying to learn for my Ecology class and I’m stuck. Can you help?

Write a 200 word caption of the photo that accurately identifies an ecological concept or principle that you recognize as visible or involved in the image.

identify any flora (plants) or fauna (animals) associated with your issue (genus species and common name). I encourage you to use the iNaturalist.org crowdsourcing nature app to get help identifying a species of interest

So I took a picture of three water-forest pictures so you can choose one of the pictures and then write about it. This is taken in Graue Mill in Illinois so if you could talk about that would be great!
