Shorebirds have beaks of different shapes and sizes that allow them to prey upon particular mudflat animals. These unique traits that allow the birds to be successful in their environment are called:

• flaws

• adaptations

• genes

• learned behaviors

NGSS.MS-LS4-4

The soft bottom of estuaries, with fine silty material, that can become exposed at low tide. Common in areas with a large tidal range, and gently sloping bottom:

• salt wedge

• salt marsh

• mangal

• mudflat

Just above the mudflats, these are extensive grassy areas that sometimes flood at high tide:

• mudflats

• manglars

• oyster reefs

• salt marshes

The movement (diffusion) of water to the hypertonic solution, across a semipermeable membrane.

• hydrolysis

• osmosis

• outwelling

• active transport

Most estuarine organisms are ____________________________, meaning they can tolerate a wide range of salinity. They can survive extreme changes in salinity.

• freshwater only

• stenohaline

• brackish water only

• euryhaline

Species of aquatic organisms that cannot tolerate changes in salinity; they are able to live within a narrow range of salinity.

• stenohaline

• euryhaline

• thermohaline

• pneumatophores

Common in Alaska, Norway, Greenland, Chile, and New Zealand, these estuaries were caused by glaciers:

• coastal plain estuaries

• bar-built estuaries

• fjords

• tectonic estuaries
