Why is an estuary like a… Sponge? An estuary soaks up water. As excess rains flood rivers and streams, wetlands form to absorb water that may otherwise flood dry living areas needed by both animals and people. Hotel? As birds migrate hundreds and thousands of miles across North America, they stop in marshes and estuaries to eat and rest before continuing on their journey. Egg beater? A coastal wetland is a place for nutrient-rich freshwater from a river or stream to mix with saltwater from the bays. As plants photosynthesize, oxygen is added to the mix. Fishes and shellfish take advantage of this life-giving soup. Cradle? An estuary provides a protective haven for young animals: plenty of food and places to hide from predators. Sea grasses and other vegetation give cover.
Strainer? The grasses of an estuary act like a sieve. Soil, branches, leaves, and even trash that has washed into the estuary are strained. This allows cleaner water to pass on downstream and into the Gulf of Mexico. Cereal? Plants absorb nutrients and help cycle them through the food web. As the grasses of the estuaries decay, or rot, a nutritious food for animals and fertilizer for other plant life are supplied. Soap? Estuaries trap, neutralize, and decompose sewage and other wastes. Excess nutrients and chemical toxins are absorbed as well. Through chemical reactions and processing by plants, water is cleaned before it passes downstream.
