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

All of the following are adaptations of mesopelagic fishes except: Nonspecific diet. Large body. Extensible jaw. Large mouth.

manatee

Order Sirenia

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

producer

kelp

producer

sargassum

producer

Nekton

swims for its entire life

The function of a swim bladder is:

to allow a fish to change position in the water column.
