What is an estuary ecosystem?

Estuarine ecosystems. These are areas where both ocean and land contribute to a unique ecosystem. A basic feature is the instability of an estuary due to the ebb and flood of the tide. Plant and animal wastes are washed away, sediment is shifted and fresh and salt water are mixed.

What is a type of estuary?

The four major types of estuaries classified by their geology are drowned river valley, bar-built, tectonic, and fjords. In geologic time, which is often measured on scales of hundreds of thousands to millions of years, estuaries are often fleeting features of the landscape.

Is estuary a freshwater ecosystem?

An estuary is a partially enclosed, coastal water body where freshwater from rivers and streams mixes with salt water from the ocean. Estuaries, and their surrounding lands, are places of transition from land to sea.

Are estuaries wetlands?

What kind of ecosystem where freshwater meets a saltwater?

Estuaries are the borderlands between salt- and freshwater environments, and they are incredibly diverse both biologically and physically. The diversity and the high energy of the ecosystem make estuaries remarkably resilient.

Why estuary called nursery of the sea?

In tight quarters, the larger fish are also exposed to a higher risk of predation from even larger animals such as birds and otters. For this reason, estuaries are often referred to as nurseries.

What are facts about estuaries?

What plants are found in estuaries?

Estuaries are usually filled with shallow waters, and sunlight reaches all levels of the water. Marsh grasses, algae, and other kinds of plants live in estuaries and provide food for a variety of fish, crabs, oysters, and shrimp.
