    Which animals are filter feeders - ProProfs

    Which animals are filter feeders

    • Clams and mussels

    • Octopuses and squid

    • Snails and slugs

    • Starfish and sea urchins

    • Jellyfish and sea anemones

    Correct Answer
    A. Clams and mussels
    Explanation
    Clams and mussels are filter feeders because they obtain their food by filtering water and extracting small particles, such as plankton and detritus, from it. They have specialized structures called gills that help them filter the water, trapping food particles and allowing them to consume them. This feeding strategy is common among bivalve mollusks like clams and mussels, as it allows them to efficiently extract nutrients from the water column.

    Marine algae is found in which sequence from sea surface to deeper water? - ProProfs

    Marine algae is found in which sequence from sea surface to deeper water?

    • Green, brown, red

    • Red, brown, green

    • Green, red, brown

    • Brown, green, red

    • Red, green, brown

    Correct Answer
    A. Green, brown, red
    Explanation
    Marine algae is found in a sequence from sea surface to deeper water as green, brown, red. This is because green algae are commonly found in the shallowest waters near the surface, where they can receive ample sunlight for photosynthesis. Brown algae are typically found at slightly deeper depths, where they can still access enough light for photosynthesis but are also able to withstand more turbulent water conditions. Red algae are found in the deepest waters, as they are adapted to low light levels and can thrive in the absence of direct sunlight.

    An individual coral animal is known as a/an - ProProfs

    An individual coral animal is known as a/an

    • Zooxanthella

    • Polyp

    • Sponge

    • Alga

    • Zooxanthella or polyp; both are correct

    Correct Answer
    A. Polyp
    Explanation
    A coral polyp is the individual coral animal that forms the foundation of a coral colony. It is a tiny, cylindrical organism that attaches itself to a hard surface and secretes a calcium carbonate skeleton. The polyp has a mouth surrounded by tentacles that it uses to capture food and tiny algae called zooxanthellae, which live symbiotically within the polyp's tissues. The zooxanthellae provide the polyp with essential nutrients through photosynthesis, while the polyp provides the algae with a protected environment. Therefore, the correct answer is "polyp."

    Animals that continually burrow through the sediments are usually - ProProfs

    Animals that continually burrow through the sediments are usually

    • Filter feeders

    • Predators

    • Deposit feeders

    • Grazers

    • Carnivores

    Correct Answer
    A. Deposit feeders
    Explanation
    Animals that continually burrow through sediments are usually deposit feeders. This means they obtain their food by consuming organic matter and nutrients that are present in the sediments. These animals often have specialized adaptations, such as sifting or filtering structures, to extract food particles from the sediment. By continuously burrowing and ingesting sediments, deposit feeders play an important role in nutrient cycling and sediment reworking in aquatic ecosystems.

    • Filter feeders

    • Herbivores

    • Deposit feeders

    • Detritus feeders

    • Grazers

    Correct Answer
    A. Filter feeders
    Explanation
    Filter feeders are animals that live on bits and pieces of organic material that are washed in from the sea or off the land. They use specialized structures or mechanisms to filter out food particles from the water or sediment. This allows them to obtain nutrients and energy from the organic material present in their environment. Examples of filter feeders include baleen whales, clams, and barnacles.

    • Copepods feeding on diatoms and dinoflagellates

    • Bacteria associated with hydrothermal vents

    • The same as krill

    • Members of the meroplankton

    Correct Answer
    A. Dinoflagellates living in tropical corrals
    Explanation
    Zooxanthellae are a type of dinoflagellates that live in tropical corals. Corals have a mutualistic relationship with zooxanthellae, where the corals provide shelter and nutrients to the zooxanthellae, and in return, the zooxanthellae provide energy through photosynthesis. This relationship is crucial for the survival and growth of coral reefs.

    Which organisms burrow into the deep-ocean muds causing a process called bioturbation? - ProProfs

    Which organisms burrow into the deep-ocean muds causing a process called bioturbation?

    • Starfish

    • Sponges

    • Sea cucumbers

    • Clams

    • Sea urchins

    Correct Answer
    A. Sea cucumbers
    Explanation
    Sea cucumbers burrow into the deep-ocean muds causing a process called bioturbation. Bioturbation refers to the disturbance of sediment layers by the activities of organisms, which helps to mix and oxygenate the sediment, promote nutrient cycling, and create habitats for other organisms. Sea cucumbers use their tube feet to burrow into the mud, ingesting the sediment and extracting organic matter from it. Their burrowing activities contribute to the overall health and productivity of deep-ocean ecosystems.

    Detritus is - ProProfs

    Detritus is

    • Important in marine food webs

    • Reworked deep-sea sediment by worms and sea cucumbers

    • Former plant/animal material degraded by decomposers

    • Important in marine food webs and reworked deep-sea sediment by worms and sea cucumbers are correct

    • Important in marine food webs and former plant/animal material degraded by decomposers are correct

    Correct Answer
    A. Former plant/animal material degraded by decomposers
    Explanation
    Detritus refers to the dead plant and animal material that is broken down and degraded by decomposers. This decomposed material is an important source of nutrients in marine ecosystems and plays a vital role in marine food webs. The reworking of deep-sea sediment by worms and sea cucumbers is a separate process and not directly related to the definition of detritus. Therefore, the correct answer is "former plant/animal material degraded by decomposers."

    The relationshpi between the clown fish and the sea anemone is called

    • Symbiosis

    • Commensalism

    • Mutualism

    • Symbiosis and commensalism

    • Symbiosis and mutualism

    Correct Answer
    A. Symbiosis and mutualism
    Explanation
    The relationship between the clown fish and the sea anemone is an example of symbiosis and mutualism. Symbiosis refers to a close and long-term interaction between two different species, where at least one species benefits. Mutualism is a type of symbiotic relationship where both species involved benefit from the interaction. In this case, the clown fish benefits by finding protection among the stinging tentacles of the sea anemone, while the sea anemone benefits from the clown fish's presence by getting rid of parasites and receiving nutrients from their waste.
