Answer:

Explanation:

The dissolved oxygen in water refers to the amount of oxygen that is found in water. However, there are various ways that oxygen dissolves in a body of water, these includes;

- Diffusion from the atmosphere: Oxygen from air or atmosphere also dissolves in water

- aeration as water moves over rocks and debris, and from wind and waves

However, humans do not exhale oxygen but carbon dioxide, hence, it is not a source of dissolved oxygen
