How does water level affect organisms in the subtidal zone?
-
Organisms need to be able to breathe water or hold their breath for long periods of time.
-
Organisms need to adapt to alternating between being exposed or submerged.
-
Organisms need to adapt to alternating between breathing or being submerged.
-
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 correct answer states that organisms in the subtidal zone need to be able to breathe water or hold their breath for long periods of time. This is because the water level in the subtidal zone can vary, and organisms need to adapt to these changes in order to survive. When the water level rises, organisms need to be able to breathe underwater. When the water level recedes, they need to be able to hold their breath until they are submerged again. This ability to adapt to changing water levels is crucial for the survival of organisms in the subtidal zone.Rate this question:

Correct Answer
A. Between the high and low tide linesExplanation
The intertidal zone is the area between the high and low tide lines. This means that it is the region of the shoreline that is covered by water during high tide and exposed during low tide. It is a unique and dynamic environment that is constantly changing due to the ebb and flow of the tides. Organisms that live in this zone must be adapted to withstand both the pounding waves and the exposure to air and sunlight during low tide.Rate this question:

Why are dunes made of finer sand than the beaches?
-
Waves deposit the fine sand on to the dune.
-
Saltation carries only the finest of beach sand.
-
Saltation mixes salt with sand making it more fine.
-
Fine sand is more porous
Correct Answer
A. Saltation carries only the finest of beach sand.Explanation
Saltation is the process by which sand particles are transported by wind in a bouncing motion. During saltation, the larger and heavier sand particles tend to settle closer to the ground, while the finest and lighter particles are carried higher in the air. As a result, when these finer sand particles are deposited, they accumulate to form dunes. This explains why dunes are made of finer sand than the beaches.Rate this question:

Along the shoreface.
-
In the intertidal zone.
Correct Answer
A. At the high tide line.Explanation
Debris and detritus are deposited at the high tide line because this is the area where the highest point of the tide reaches before receding. As the tide comes in, it carries with it various types of debris and detritus, such as seaweed, shells, and other organic matter. When the tide reaches its highest point, it deposits this material along the high tide line. This line marks the boundary between the land and the water, and it is where the majority of the debris and detritus will accumulate.Rate this question:

Phytoplankton are_______________________
-
Free floating microscopic plants that are the basis of the marine food chain.
-
Free floating microscopic animals that are the basis of the marine food chain.
-
Free floating microscopic scavengers that support the marine food chain.
-
Diatoms that cause red tide and are toxic to the marine food chain.
Correct Answer
A. Free floating microscopic plants that are the basis of the marine food chain.Explanation
Phytoplankton are free floating microscopic plants that are the basis of the marine food chain. They are responsible for producing the majority of the Earth's oxygen and are consumed by various marine organisms, starting the food chain. They play a crucial role in maintaining the balance of marine ecosystems and are essential for the survival of many marine species.Rate this question:

Most supratidal animals are ____________ that feed on debris and detritus along the strand line.
-
Scavengers
-
Decomposers
-
Producers
-
Herbivores
Correct Answer
A. ScavengersExplanation
Supratidal animals are organisms that live in the area above the high tide line. These organisms rely on debris and detritus, which are dead organic matter, as a food source. Scavengers are organisms that feed on dead and decaying organisms, making them the most suitable answer. Decomposers break down dead organic matter, producers create their own food through photosynthesis, and herbivores consume plants as their primary food source, none of which accurately describe the feeding habits of supratidal animals.Rate this question:

A gastropod is a mollusk that has two shells it is a bivalve or pelecypod with a strong muscular foot.
-
A gastropod is a mollusk that attaches itself to hard substrate to survive.
-
A gastropod is a mollusk that has an internal shell like a squid.
Correct Answer
A. A gastropod is a mollusk that has one shell. It is a marine snail.Explanation
A gastropod is a type of mollusk that has one shell. It is specifically referred to as a marine snail. This means that it is a snail that lives in the ocean and has a single shell to protect its soft body.Rate this question:

Coarse sand settles in the intertidal zone because:
-
Turbulent ocean waves can carry coarse sediment and deposit it on the shoreline.
-
Turbulent ocean tides can carry coarse sediment and deposit it on the shoreline.
-
Gentle sound waves deposit coarse sediment in the ebb tidal deltas.
-
The longshore current carries coarse sediment to the shore.
Correct Answer
A. Turbulent ocean waves can carry coarse sediment and deposit it on the shoreline.Explanation
Turbulent ocean waves have enough energy to pick up and transport coarse sand particles. As these waves approach the shoreline, their energy decreases, causing them to deposit the sediment they were carrying. This process is known as wave deposition. Therefore, coarse sand settles in the intertidal zone because turbulent ocean waves can carry it and deposit it on the shoreline.Rate this question:

Tides- the daily cycle of 2 high and 2 low tidal flow of water onto and into a low lying shore area caused by the:
-
Moon and sun’s gravitational pull on Earth.
-
The gravitational pull of the tilt of the Earth on its axis.
-
Sun’s gravitational pull on Earth.
-
The oceans wave energy.
Correct Answer
A. Moon and sun’s gravitational pull on Earth.Explanation
The tides are caused by the gravitational pull of the moon and the sun on Earth. The moon's gravity is stronger than the sun's, so it has a greater influence on the tides. As the moon orbits around Earth, its gravitational pull causes a bulge of water on the side of Earth facing the moon, creating a high tide. On the opposite side of Earth, there is also a high tide due to the centrifugal force caused by the moon's gravitational pull. This results in two high tides and two low tides every day. The sun's gravity also contributes to the tides, but to a lesser extent.Rate this question:

The action of ____________________ sweeps larger shell particles and sand across the substrate surface, sometimes causing abrasions or burying plants and animals.
-
Waves
-
Tides
-
Longshore current
-
Winds
Correct Answer
A. WavesExplanation
Waves have the ability to move larger shell particles and sand across the substrate surface. This movement can sometimes lead to abrasions or burying of plants and animals. Waves, with their back and forth motion, exert a strong force on the particles and can cause them to be transported along the shoreline. This action is known as wave action and is responsible for shaping coastal landscapes and affecting the distribution of organisms in these habitats.Rate this question:

Which organism causes "red tide" scientific name: pfiesteria piscicida?
-
Dinoflagellates
-
Diatoms
-
Gastropods
-
Pelecypods
Correct Answer
A. DinoflagellatesExplanation
Dinoflagellates are the organisms that cause "red tide" and the scientific name for the specific organism causing red tide is Pfiesteria piscicida. Dinoflagellates are a type of planktonic algae that are capable of photosynthesis. They are known for their ability to reproduce rapidly, leading to large blooms or "red tides" in coastal waters. These blooms can deplete oxygen levels in the water, leading to the death of fish and other marine organisms. Pfiesteria piscicida is a specific species of dinoflagellate that has been associated with fish kills and harmful effects on human health.Rate this question:

Correct Answer
A. Most supratidal animals are__scavengers_________ that feed__on debris along the____ strand line____Explanation
Most supratidal animals are scavengers that feed on debris along the strand line. Supratidal animals are those that live above the high tide line, and they rely on scavenging for their food. The strand line is the area where debris from the ocean washes up on the shore, providing a food source for these animals. By feeding on the debris, they are able to obtain nutrients and sustain themselves in their habitat.Rate this question:

What is a mollusk?
-
An organism with a hard shell that encases a soft muscle body
-
An organism with a soft shell and a hard interior skeleton
-
A bottom dwelling organism that breathes water and uses siphons to feed
-
A bottom dwelling organism that uses a muscular foot to dig and capture its prey
Correct Answer
A. An organism with a hard shell that encases a soft muscle bodyExplanation
A mollusk is an organism with a hard shell that encases a soft muscle body. This hard shell provides protection and support for the soft body inside. Mollusks can be found in various environments, such as oceans, freshwater, and even on land. They are a diverse group of animals that includes snails, clams, octopuses, and squids. The soft muscle body of a mollusk allows for movement and various functions such as feeding, reproduction, and respiration. The hard shell is typically made of calcium carbonate and can vary in shape and size depending on the species.Rate this question:
