Marine Biology 9
| Question | Answer |
|---|---|
| The __________ zone is the area of shoreline between high and low tides. | intertidal |
| It is a relatively small zone but has the greatest variation of _________ as compared to any other marine system. | environmental factors |
| The bottom surface, or _________ , of a marine habitat determines what organisms can live there. | substrate |
| Another name for intertidal zone? | littoral zone |
| The two basic types of substrate are ___________ and ___________. | rocky and sandy/muddy |
| Animals that hold onto the surface of a substrate are called __________. | epifauna |
| When such an organism is attached to a substrate, it is called_________ | sessile |
| Most organisms living in the upper areas of the intertidal zone face becoming dried out, or __________, during low tide. | dessicated |
| Often they move to small areas of trapped water called________ | tide pools |
| Besides moisture level, two abiotic factors that can drastically change during low tide are_________ and _____________ | temperature; salinity fluctuations |
| What structures in the water slow down waves? | coral reefs, sandbars, and canyons |
| When an area juts out farther than the rest of the coast it is a ___________ | headland |
| A________ is an area of coast behind the rest of the shoreline. | bay |
| On the ocean bottom, sudden depressions, called ________, cause waves to bend so that the shoreline wave action is ______. | canyons; weak |
| Noticeable horizontal bands of organisms living within a certain range in the intertidal zone are known as ____________ | vertical zonation |
| The upper limit in which an organism can live is usually determined by _________, such as too much sunlight, while the lower limit is usually a result of _________, such as predation. | abiotic factors; biotic factors |
| The three major zones of organisms within the rocky intertidal are the ______,_________, and _______ zones. | upper, middle, lower |
| The highest zone is rarely submerged, extending from the highest spring tide mark to the ____________________ | extent of water spray caused by waves |
| The limiting factor here, then is _________ | water |
| The middle zone of the intertidal has such fluctuations in __________ (such as from neap tides) | tidal patterns |
| The highest area most notably contains __________ | barnacles |
| The middle area of this center zone is dominated by aggressive ______. | mussels |
| The most limiting factor in the middle area is ________ | space |
| The lower levels of the middle intertidal zone commonly contain species of ________ which are ________ signaling the lower limits of this area. | algae; indicator species |
| When a specific area becomes available for occupation, the process of the habitation of that area is called, ____________. | ecological succession |
| When dominant species finally move into an area and become established for an extended period, that area is called a ________________ | climax community |
| The limiting resources of the lower intertidal zone are _________ and ________. | space; light |
| This zone is under water most of the time and has the ___________ diversity of intertidal organisms. | greatest |
| Biotic factors that lower the limit that an organism can live | predation and competition |
| There are relatively few _________ producers in a soft- bottomed ecosystem | primary |
| Zonation is present in soft- bottomed ecosystems but it is more pronounced in areas with a _______ substrate. | sandy |
| Sand fleas and burrowing crabs are found toward the ___________ | upper zone |
| The center zone contains ___________ that live under the substrate. | worms and clams |
| At _______ level, the diversity of species__________ and includes sand dollars and sea cucumbers | low tide; increases |
