With your group describe a short statemetn that describes the connection between nutrient levels, dissolved oxygen, biological oxygen demand, plants, fish, and decomposers

When there is an excess amount of nutrients for water plants, Eutrophication occurs. It is a form of Water Pollution. During the Eutrophication, nutrients are released from the sewage to water. With the excess amount of nutrients, algaes and other aquatic plants growth increase. When they die, decomposers use the oxygen in the water for the process. The animals and fishes will die due to lack of oxygen levels.
