Answer:
Estuaries connect land and sea. They are partly enclosed bodies of water situated at the edge of the land – a mixture of freshwater from streams and rivers and saltwater from the sea. Estuaries come in all shapes and sizes and can be called harbours, inlets, bays, lagoons, sounds, wetlands and swamps. They are the nurseries of oceans. Many fish and shellfish are spawned in estuaries. Full of nutrients and home to resilient organisms, estuaries provide rich feeding grounds for fish and birds.
