<span>The amount of dissolved oxygen in water may decrease
because of the increase in organic matter in the water. <span>Aquatic organisms breathe and use oxygen. Large amounts of
oxygen are consumed by the decomposition of bacteria (when there are large
amounts of dead matter to decompose, there will be a significant number of
bacteria). Examples: dead organic matter (algae), wastewater, garden waste,
oils and fats, all this results in a decrease in dissolved oxygen in the water.</span></span>

<em>It is the process in which green plants make their food through a green pigment known as Chlorophyll by using sunlight, Carbon-dioxide and water</em>. <em>The result comes out with the formation of Oxygen as a byproduct. But in night they also respire like animals and photosynthesis does not occur. Photo means light and synthesis means manufacture.</em>
