An area of land that is sometimes underwater or whose soil contains a great deal of moisture, is called wetlands An area of land that is sometimes underwater or whose soil contains a great deal of moisture, is called wetlands It plays an important role in flood control. During heavy rains and springs snow melt, wetlands soak up large amounts of water. It plays an important role in flood control.

A treeless wetland ecosystem where plants, such as grasses grow is called marshes. A treeless wetland ecosystem where plants, such as grasses grow is called marshes. Found in shallow areas along the shores of lakes, ponds, rivers, and streams. Found in shallow areas along the shores of lakes, ponds, rivers, and streams. Plants vary depending on depth of water and location. Plants vary depending on depth of water and location. Grasses, reeds, bulrushes, and wild rice are common marsh plants.

Water quality is how good the water is. Water quality is how good the water is. It messes up the food chain for animals, plants, and humans. It messes up the food chain for animals, plants, and humans. Its important because we use water to drink and we could get sick. Its important because we use water to drink and we could get sick. The plants and animals need water to survive and if they dont have water the people that go hunting wont have food and herbivores dont have plants to eat.

Water and air temperatures are factors of water quality. Water and air temperatures are factors of water quality. They affect water quality because of how much gas is dissolved in the water. They affect water quality because of how much gas is dissolved in the water. We use thermometers to test water and air temperature. We use thermometers to test water and air temperature.

Turbidity is a factor of water quality. Turbidity is a factor of water quality. The turbidity affects water quality because it can block the light to aquatic plants, smother aquatic organisms, and it carries contaminates and pathogens.

Dissolved oxygen also is a factor of water quality. Dissolved oxygen also is a factor of water quality. It is important to the plants and fish because they must have oxygen to survive. It is important to the plants and fish because they must have oxygen to survive. You measure dissolved oxygen by using an ampoule. You measure dissolved oxygen by using an ampoule.

Sediment size is another factor of water quality. Sediment size is another factor of water quality. Sediment size also affects the fish because they could hide, or lay their eggs in large sediments, and they could lose them. Sediment size also affects the fish because they could hide, or lay their eggs in large sediments, and they could lose them. We test sediment size by putting sand from the ocean on the paper and comparing it to the dots of the paper.
