Barrier Islands Proprof Quiz # 1 2018

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.

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.

The subtidal zone is found below the water line. This refers to the area that is permanently submerged underwater, even during low tide. It is the region where marine organisms live and thrive, and it is characterized by its constant exposure to water.

A barrier island is a long, narrow body of sand that is separated from the mainland by a sound and is also separated from other islands by inlets at both ends.

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.

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.

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.

The intertidal zone is the area that is located between the high and low tide lines. This zone is exposed to the air during low tide and submerged during high tide. It is characterized by a diverse range of organisms that are adapted to survive in both marine and terrestrial conditions.

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.

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.

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.

The correct answer is "Bottom material organisms live in or on." This option accurately describes the term "substrate" as the material that provides a surface for organisms to live on or in. It refers to the physical environment where organisms can attach or burrow, such as rocks, sediments, or other solid surfaces in the ocean.
