    How does water level affect organisms in the subtidal zone?

    • A.

      Organisms need to be able to breathe water or hold their breath for long periods of time.

    • B.

      Organisms need to adapt to alternating between being exposed or submerged.

    • C.

      Organisms need to adapt to alternating between breathing or being submerged.

    • D.

      Organisms need to adapt to alternating between being submerged or holding their breath for long periods of time.

    Correct Answer
    A. Organisms need to be able to breathe water or hold their breath for long periods of time.
    Explanation
    The water level in the subtidal zone affects organisms because they need to be able to breathe underwater or hold their breath for long periods of time. This is because the subtidal zone is a part of the ocean that is always submerged, so organisms living in this zone need to have adaptations that allow them to survive in an underwater environment.

    Match the location where the supratidal zone is found.

    • A.

      Between the high and low tide lines

    • B.

      Above the high tide line

    • C.

      Below the high tide line

    • D.

      Between the sand bar and the berm

    • E.

      Between the swash zone (shoreface where waves break) and the dune

    Correct Answer
    B. Above the high tide line
    Explanation
    The supratidal zone is found above the high tide line. This means that it is the area on the shore that is not reached by the highest tides. It is typically dry and only gets wet during extreme high tides or storm surges. This zone is also known as the splash zone, as it is occasionally splashed by waves but not submerged in water on a regular basis.

    Rate this question:

  • 6. 

    What is a berm and where is it found?

    • A.

      The back dune end of the supratidal zone

    • B.

      The movement of sand offshore during a storm

    • C.

      The supratidal ledge of sand at the high tide line

    • D.

      The edge of the swash (shoreface where waves break) zone

    Correct Answer
    C. The supratidal ledge of sand at the high tide line
    Explanation
    A berm is a supratidal ledge of sand that is found at the high tide line. It is a raised area of sand that acts as a natural barrier between the beach and the land behind it. The berm is formed by the deposition of sand and sediment brought in by waves and tides. It helps to protect the land from erosion and provides a buffer zone between the ocean and the coastal area.

      Canadian and Gulf of Mexico currents

    • D.

      Coast of Greenland and Gulf Stream currents

    • E.

      Between the swash zone (shoreface where waves break) and the dune

    Correct Answer
    A. Laborador/Virginia and the Gulf Stream currents
    Explanation
    The correct answer is Laborador/Virginia and the Gulf Stream currents. These two major currents have a significant impact on North Carolina's climate. The Laborador/Virginia current is a cold current that flows southward along the coast, bringing cooler temperatures to the region. The Gulf Stream current, on the other hand, is a warm current that flows northward just offshore, bringing warmer temperatures to the area. The interaction between these two currents influences the temperature and weather patterns in North Carolina.

    What is the original source of energy for the entire seashore community?  

    • A.

      The original source of energy is the sun.

    • B.

      The original source of energy is the ocean.

    • C.

      The original source of energy are the producers.

    • D.

      The original source of energy is the moon and tides.

    Correct Answer
    A. The original source of energy is the sun.
    Explanation
    The sun is the original source of energy for the entire seashore community. It provides sunlight, which is essential for photosynthesis in plants, the primary producers in the ecosystem. These producers convert solar energy into chemical energy through photosynthesis, which is then transferred to other organisms in the food chain. Thus, the sun is the ultimate source of energy that sustains the entire seashore community.

    How is energy passed through the community?  

    • A.

      Energy is passed through the community through feeding relationships.

    • B.

      Energy is passed through the community as organisms move about their habitat.

    • C.

      Energy is passed through the community through organism decomposition.

    • D.

      Energy is passed through the community as organisms breed and grow.

    Correct Answer
    A. Energy is passed through the community through feeding relationships.
    Explanation
    Energy is passed through the community through feeding relationships. This means that energy is transferred from one organism to another as they consume each other. This process occurs in a food chain or food web, where energy flows from producers (plants) to primary consumers (herbivores) to secondary consumers (carnivores) and so on. Each organism obtains energy by consuming other organisms, and this energy is then used for growth, reproduction, and other life processes. Feeding relationships are essential for the transfer of energy and the functioning of ecosystems.

    What are the three basic components of a food web?

    • A.

      Three basic components of a food web are producers, consumers and decomposers.

    • B.

      Three basic components of a food web are producers, consumers, scavengers and decomposers.

    • C.

      Three basic components of a food web are producers, bacteria and fungi.

    • D.

      Three basic components of a food web are autotrophs, heterotrophs and heliotrophs.

    Correct Answer
    A. Three basic components of a food web are producers, consumers and decomposers.
    Explanation
    The correct answer is "Three basic components of a food web are producers, consumers and decomposers." This answer accurately identifies the three main groups of organisms involved in a food web. Producers, such as plants or algae, convert sunlight into energy through photosynthesis. Consumers, including animals, obtain energy by consuming other organisms. Decomposers, such as bacteria and fungi, break down dead organic matter and recycle nutrients back into the ecosystem. These three components are essential for the flow of energy and nutrients within a food web.

    Rate this question:

  • 14. 

    What effect does the elevation and slope of the island have on habitats?

    • A.

      Elevation and slope determine how far a tidal zone extends into a habitat.

    • B.

      Elevation and slope determine how much erosion is in a habitat.

    • C.

      Elevation and slope determine the producers in a community.

    • D.

      Elevation and slope determine the size of the barrier island.

    Correct Answer
    A. Elevation and slope determine how far a tidal zone extends into a habitat.
    Explanation
    The elevation and slope of an island can determine how far a tidal zone extends into a habitat. This is because the elevation and slope affect the movement of water and the level of tidal influence. If an island has a steep slope, the tidal zone may be limited to a smaller area, whereas a gentle slope may allow the tidal zone to extend further inland. Similarly, a higher elevation may result in a larger tidal zone, while a lower elevation may restrict the tidal influence. Therefore, the elevation and slope of an island directly impact the extent of the tidal zone within a habitat.
