Watersheds are important because the surface water features and stormwater runoff within a watershed ultimately drain to other bodies of water. It is essential to consider these downstream impacts when developing and implementing water quality protection and restoration actions. Everything upstream ends up downstream.
Im not sure what the question is could u further define or give me the possible answers
Answer is preserve
1<em>. Removing oxygen:</em> The removal of oxygen from food preserves the food by avoiding the oxidation of food that leads to spoilage.Cover the food or vegetable tightly in air tight container to avoid oxygen reaching the cut cells which will cause spoilage of food.The fruits and vegetables should immediately be boiled or cooked to prevent oxidation.
2. <em>Removing moisture: </em>The removal of excess water from vegetables and fruits helps in preservation of food. The bacterial growth that spoils the food grows in moist environment hence reducing the moisture content will preserve food.
<em>3. Killing spoilage organism: </em>The ultraviolet light and infrared light are used to kill the organisms causing spoilage of food. Flash technique is also used for preserving food from microorganism.
