Question

Quizplus · Accepted Answer

Dissolved oxygen is a major cause of differences among aquatic ecosystems because it is a critical factor for the survival of aquatic organisms and can vary greatly between different bodies of water depending on factors such as temperature, depth, and presence of vegetation. Ammonia, urea, and dissolved ozone molecules are not as significant in causing differences among aquatic ecosystems.
