You have two identical bags and fill them with the same amount and type of leaves. You put the identical bags in two different areas of a river. After several weeks, one set of leaves has almost disappeared and the bag is full of organisms. The other set of leaves is still mostly whole and the bag has few organisms in it. Questions: What are some ways the two different areas of the river could be different? How might these differences explain why the leaf packs in one area have more organisms than the leaf packs in another area?
