Q7.Which gas is used to increase the quantity of dissolved oxygen in water ? |

Answer» Dissolved oxygen levels are increased by supplementing wind and wave action, adding plants to water and exposing water to purified oxygen. Using the latter method can result in supersaturation, or levels of oxygen in excess of natural levels Promote photosynthesis by adding rooted aquatic plants to water. Plants photosynthesize under adequate lighting conditions, adding dissolved oxygen to water. |
