Business owners get FREE listings on GuidedBy.ca. Many plant and animal species thrive in estuaries. Organisms such as fish and birds transfer nutrients as they move in and out of the estuary. The estuary is an ecosystem – a group of living and non-living things interacting with each other. Many animals rely on them for food, migration stopovers and places to breed. Most animals and plants would find it difficult to survive in a habitat that changes so much. Fish are the main type of animal that use estuaries as nurseries. Nutrients are also transferred through the nutrient cycle. Because estuaries are highly dynamic environments subject to processes occurring on the land and in the sea, the locations, sizes and types of habitats can change relatively quickly, or form over years or decades.
