Dissolved oxygen is important to our ecosystem because it is necessary for the survival of aquatic organisms, such as fish and other aquatic life forms. Oxygen is essential for cellular respiration, the process by which organisms obtain energy from food. Without sufficient dissolved oxygen in water, aquatic organisms can suffocate and die. Additionally, dissolved oxygen levels can indicate the overall health of an aquatic ecosystem, as low levels may suggest pollution or other environmental stressors.
