Why estuaries is the most productive ecosystem?

Estuaries tend to be very rich in organisms. Rivers, before they are diluted by the enormous body of ocean water, have generally high concentrations of many chemical elements needed by plants and animals to build their tissues. Organic particulates draining from the land tend to be sedimented out in the estuary.

Are estuaries the most productive ecosystems in the world?

Estuarine environments are among the most productive on earth, creating more organic matter each year than comparably-sized areas of forest, grassland or agricultural land. The sheltered waters of estuaries also support unique communities of plants and animals specially adapted for life at the margin of the sea.

Why do estuaries have low global productivity?

Although estuaries export nutrients to the sea, they are also nutrient traps in that nutrients build up in tidal pools, deep water areas, salt marshes and adjacent wetlands. … Without eutrophic conditions, estuaries would not be the highly productive systems they are and would not have excess nutrients to export.

What characteristics make an estuary such a productive ecosystem?

Estuaries are very biologically productive. The salinity gradient and the changes in tides, fresh water and accompanying flux in nutrients within estuaries create a variety of habitats that support a diverse food web.

How do estuaries affect the environment?

Sediments and nutrients

Sediments infill estuaries and can smother marine life. Excessive nutrients cause eutrophication and excessive growth of algae. Algal blooms are becoming common in many estuaries. Eutrophication poses a serious threat to estuarine ecosystems.

Why is Estuary and intertidal zone important to our environment?

Estuaries support a diversity of species of fish, shellfish, aquatic plants and animals. The protected waters provide vital nesting, breeding and feeding habitats for many species. Estuaries also filter pollutants out of the water flowing through them, including pesticides, herbicides and heavy metals.
