EcoBook #28- Eutrophication
The example in this picture is algae that represents how an over abundance of it in lakes or other body of water can cause a pollution called Eutrophication which takes away oxygen in the water killing many aquatic organisms. This is a sign where a body of water becomes rich with nutrients.
That is the definition of eutrophication, but this looks like it's just algae on a wall? +2
