Important marine autotrophs that have silica incorporated into their cell walls are
diatoms.
Primary productivity in temperate marine systems is limited solely by the amount of available solar radiation.
False
Sharks have lunate caudal fins.
False
Species diversity and total biomass are greater in warm-water marine environments in comparison to cold-water marine environments.
False
The products of photosynthesis are carbon dioxide (CO2) and water (H2O).
False

Bacteria that manufacture carbohydrates in the absence of solar energy are autotrophs.
True
Many cetaceans can extract 90% of the oxygen from each breath.
True
One reason that polar climates support a higher biomass is that colder water can hold more dissolved oxygen than warmer water.
True
Red muscle tissue is abundant in cruisers, while white muscle tissue is abundant in lungers.
True
The California gray whale is unusual because it stirs up bottom sediment in order to feed.
True
Which of the following affect the ability of species to capture food? speed body temperature circulatory system body length All of these affect the ability of pelagic organisms to capture food.
All of these affect the ability of pelagic organisms to capture food.
All of the following are benefits of the adaptive behavior in the figure because it: reduces the probability that a predator will locate the prey species. confuses predators by constantly changing positions of the fish within the school. makes the group of fish appear as one large unit. reduces the mortality rate for individuals within the school. All of these behaviors are beneficial to schooling fish.
All of these behaviors are beneficial to schooling fish.
A small size is advantageous for marine organisms because it
All of these statements are advantageous to marine organisms
Multicellular, eukaryotic organisms that range in complexity from simple sponges to complex vertebrates belong to the kingdom
Animalia
An overabundance of organic matter results in eutrophication.
False
Equatorial upwelling decreases primary productivity in tropical waters.
False
The distinction between a food chain and a food web is that a food chain describes a linear relationship among trophic levels whereas a food web describes the interconnected relationships among trophic structures in nature.
True
The hadal zone is associated with deep-ocean trenches.
True
The neritic province is associated with the continental shelf.
True
We currently believe that all marine mammals evolved from land-dwelling mammals.
True
Neritic marine environments would be found
associated with continental shelves
Plankton
can never swim against a current
flounder
consumer
starfish
consumer
Meroplankton
floats for a portion of its life
Productivity in polar oceans is
light-limited.
Infauna
lives in benthic sediments
Epifauna
lives on top of benthic sediments
High-latitude ocean water tends to support large planktonic communities because
of higher dissolved oxygen and nutrient concentrations
The process by which energy is derived from solar radiation that is used by certain organisms to form organic matter is called
photosynthesis.
The relative productivity in the world's oceans from most productive to least productive is
polar waters, temperate waters, tropical waters.
Planktonic organisms often have needle-like structures that
prevent sinking
algae

kelp

sargassum

Nekton
swims for its entire life
The function of a swim bladder is:
to allow a fish to change position in the water column.
