Question

Quizplus · Accepted Answer

Oxygen is primarily produced by photosynthesis, which is the process by which plants, algae, and some bacteria use energy from the sun to produce oxygen from carbon dioxide and water. While decomposition and respiration can consume oxygen, they are not sources of oxygen in a water body. Similarly, while evaporation can increase oxygen levels in the atmosphere, it does not produce oxygen in the water itself.
