Dissolved oxygen





Oxygen (O2) is a substance that is important for the life of organisms.

Oxygen is needed by aquatic organisms to breathe.

fish in water need oxygen to breathe.

oxygen can dissolve into water through a diffusion process.

the factors that can affect the amount of oxygen that dissolves in water are as follows:

1. temperature. temperature affects the saturation of water (the capacity of water to absorb oxygen). When the water temperature is high, less oxygen will dissolve.

2. Surface water movement. movement of surface water in the form of waves will accelerate the process of diffusion of air into the water.

3. Air pressure. This air pressure is related to the height of a place above sea level. if an area is higher then the air pressure will be low so that dissolved oxygen will be low.

4. salinity. the higher the salinity value, the less dissolved oxygen will be.

5. aquatic plants. aquatic plants associated with photosynthesis. the photosynthesis process will produce oxyg…
