Healthy Unhealthy
Overpopulation Clean Water Clear water Litter, cloudy water biodiversity (lots of plants and animals) fewer plant and animal species less dissolved oxygen (DO) Plenty of DO (dissolved
Algae Cool water temp. warm water temp. Nitrogen Dissolved Oxygen sewage in water lots of bacteria (pathogens)

Healthy Unhealthy
Good levels of Dissolved Oxygen (DO) Mutations Biodiversity (lots of plant and animal species) trash, litter, pollution smells fishy water is moving (flow) water not moving (stagnant) Not enough resources for the organisms (food, space, shelter etc) clear water cloudy, murky water gooey or slimey water algae Nitrogen vegetation around the area (shading water) fewer plants and animals
