Question | Answer |
Intertidal zone | Area of shoreline between high and low tides |
Sessile | Organism attached to a substrate |
Desiccated | something dried out |
Vertical zonation | noticeable horizontal bands of organisms living within a certain range in the intertidal zone |
Ecological succession | a gradually increasing occupation of new organisms into a specific area |
What are two major types of substrates? | 1. Rocky 2. Sandy/muddy |
What is the difficulty and benefit of the wave action in the intertidal zone? | difficulty - in high tide it can wash away adapted organisms; its benefits - waves can wash away accumulated wastes and bring nutrients into an area |
How does a non sessile organism use high tide to avoid being thrown by the waves? | They can roll with the waves or move to a crevice where it will be protected |
Know about temperature and salinity in a tide pool and how it changes with the tides | During low tide the tide pool becomes more vulnerable to temperatures, salinity levels can decrease with rain because of fresh water, but increase when heat evaporates the water; temperature will rise from heat or become freezing in colder temperature |
Explain why a wave bends or refracts from shore if it comes in at an angle | As waves come closer to shore the majority of the wave is moving slowly, but the furthest edge from shore is moving more quickly to catch up |
How does the canyon or sandbar affect wave action? | Sandbar causes waves to break, Canyon causes waves to bend |
Why space is an important factor in the intertidal zone? | it is the one thing that can claim survival for an organism. |
Why does salinity and temperature affect the upper and lower limits of where organisms can live? | during low tide temperatures can get extremely cold or extremely hot, salinity can increase due to water evaporation and decrease during rainy weather |
What is a climax community? | final stage of succession, remaining relatively unchanged until destroyed by biotic or abiotic factors |
Which zone has the greatest diversity? Upper, Lower, or Middle? | Lower |
What are limiting resources in the Upper, Middle, and Lower zones? | Upper - water, Middle - space/air, Lower - light |
Which sediment allows water to move through more slowly? | mud |
Why isn't the zonation noticeable in the muddy internal zone? | the organisms bury themselves in it |
