What do you need for a fish ecosystem?

Algae, shelter, minnows, crayfish, frogs, turtles.

What are some of the things that can happen when a mine is built next to a fish ecosystem?

The animals start dying. More pollution from the mine goes in the lake. Roads are built which makes the stream smaller. If a lot of people work at the mine, everybody’s going to want to catch fish and then there will be no fish. The hot water can go back into the lake and kills the fish.
