Bio-assessing a body of water involves finding out what types of organisms live there. Conserving and protecting our water from pollution is vital to us as well as to the environment. Once in the water cycle, pollution can often travel, affecting the entire system. For example, pollution can be picked up by rain and carried to a hillside. The pollution will then seep into the ground and soil water or runoff into a stream or lake.
Plants soak up the water from the soil, and animals drink it from the streams.
In fact, most pollution is non-point source pollution, a type of pollution whose source is not readily identifiable. Give one reason good water quality is important. Identify three animals that live at least part of their lives in water. Wet rocks may be slippery, walk carefully. Watch out for poison ivy.
