The low intertidal zone only experiences exposure to air during the absolute lowest tides, and therefore organisms within it are used to living under the sea. 10 Ways to Protect Estuaries. Ecosystem – composed of living organisms called the biotic factors and non-living components called abiotic factors that interact with each other. Some of the threats to the estuary biome are:- Urban development: Housing development, recreational activities and fishing will change the environment and have an impact on estuaries. Intertidal Zone And Estuaries The Intertidal Zone has very simple organisms like Sea Urchins. Estuaries rank among the most productive ecosystems on earth, but they are also subject to considerable ecological degradation associated with the loss and alteration of habitats and impairment of water quality due to multiple anthropogenic and natural drivers of change We impact estuaries in many ways. Those organisms, in turn, serve as food for many other animals. A littoral zone organism can withstand various elements such as pounding surf and drying out at low tide. mdavis33. 0.
