|---|---|
| Periwinkle | A prominent herbivore that can be found grazing on algae at the lower edge of the supra littoral fringe of rocky shores is the |
| Mussel | A major competitor of barnacles for space on rocks is the |
| Wave Shock | The low body profile of animals that live on intertidal rocks is an adaption that protects against |
| Fucus | The most common algae in the midittoral(intertidal) zone of temperature rocky shores is |
| Wave Action | The most important factor in determining the distribution of on a sandy beach is |
| Ghost Crabs | On warm temperature and tropical sandy beaches, the dominant animal in the supratidal zone is the |
| Burrowers | Most organisms that inhabit the intertidal zone of a sandy beach are |
| Saturation | The vertical zone of the sandy beach that supports the highest number of organisms is the zone of |
| Embayment | Coastal areas where parts of the ocean is partially cut off from the rest of the sea is called an |
| Tectonic Estuary | The type of estuary formed when earthquakes cause land to sink, allowingseawater to enter is a |
| Fjord | A deep estuary that has high river input but little tidal mixing is a |
| Uniform | In a well-mixed estuary, vertical salinity is |
| Salinity | The environment factor that affects the types of organisms in estuaries more land anything else |
| Osmoconformer | If the concentation of salts is an animal's body tissues varies with the salinity of the environment the animal would be an |
| Burrowers | Most organism that inhabits mud flats are |
| Red Mangrove | The mangrove species usually closet to the water in American mangrove forest is the |
| Lugworm | An example of a deposit feeder found on mud flats would be the |
| Green Sea Turtle | An animal that feeds directly on seagrass is the |
| Characteristics that organisms exhibit would be the | ability to attach themselves to rocks to avoid being pulled into the water. |
| Challenges that are encounter for organisms in tide pools would be that | during high tide fish come up to feed. |
| To avoid desiccation, periwinkles would | bury themselves in cracks or seal the opening of their shell with mucus. |
| The adaption organisms have to survive wave shock is | burrowing themselves into sand or attaching themselves. |
| The vertical zonation of sandy beaches | Would be dry sand and many organisms like to bury themselves in the sand. |
| The difference between a salt-wedge estuary and other estuaries would be that | All the estuaries mixed but a salt-wedge freshwater flows directly into the ocean. |
| Factors that contribute to the productivity of estuaries would be | The mix of fresh and saltwater that has nitrogen, phosphorus and silica. |
| Organism that are osmoconformers adjust to the environment because | they lose or gain water in their body making them tolerant. |
| Back wash | water flowing down the beach after a wave breaks. |
| Periwinkle | A mollusc in the family Littorinidae that inhabits the upper part of the intertidal zone. |
| Wave shock | The force of waves as they crash against the rocks and the organisms that live on the rocks. |
| Tidal pool | A depression in intertidal rocks or in the intertidal zones of sandy beaches that continues to hold water during a low tide. |
| Swash | The water running up a beach after a wave shock. |
| Infauna | Benthic organisms that live in the bottom sediments. |
| Reflective beaches | A type of beach with a steep slop on which wave energy is directly dissipated. |
| Zonation | The separation of organisms in a habitat into definite zones or bands. |
| Byssal threads | Strong protein fibers secreted by mussels that fasten the animals to rocks or another solid surface. |
| Zone of drying sand | The uppermost vertical zone in the high intertidal region of a sandy shore characterized by the presence of moisture only during the highest tides. |
| Cordgrass | A plant in the genus spartina. It is the dominant vegetation in North American marsh communities. |
| Low Marsh | The portion of a salt marsh that occupies the lower intertidal zone and that covered by tidal water much of the day. |
| Negative Estuary | An estuary in which the surface water flows towards the river and the water along the bottom moves out to the sea. |
| Tidal flat | An area of estuary that is exposed at low tide and covered at high tide. |
| Embayment | An area of coastline where portions of the ocean are cut off the rest of the sea. |
| Positive Estuary | An estuary in which the surface water from the river flows out into the estuary along the bottom. |
| High Marsh | The region of a salt marsh closets to shore that is covered briefly by saltwater each day. |
| Euryhaline | Ability to tolerate a broad rang salinities. |
| Pseudofeces | Large, semisolid particles produced by bivalves and consisting of phytoplankton and detritus that they filler but do not consume. |
| fjord | Deep valley cut into the coastline by glaciers and fill with a mixture of freshwater and saltwater. |
