Chapter 12, 13, 14 AND 15.

Multicellular organisms that are comprised of eukaryotic, heterotrophic cells with cell walls would most likely belong to the kingdom

Fungi

Which of the following associations is incorrect?

Kingdom Plantae-macroalgae

Which of the following statements shows the correct hierarchical ordering of taxonomic levels in terms of increasing specificity?

Kingdom, phylum, class, order, family, genus, species

Which marine environments exhibit the greatest species diversity?

Neritic Province

An organism that tolerates a wide range of salinities is referred to as

euryhaline

When an organism has the same salt and water concentration as its environment, it is said to be

isotonic

The majority of marine invertebrates are

isotonic with respect to their environment

Planktonic organisms that spend part of their life in planktonic form, and the rest of their life as either benthos or nekton are called

meroplankton

The seasonal temperature range in the deep ocean is usually

negligable

Which of the following word pairs correctly link a descriptor with the way in which the organism lives in the ocean?

nekton-swim

Plankton which are 2.0 to 0.2 in size are called

picoplankton

An example of an organism that might be part of the epifauna is an

sea star

Organisms that cannot withstand large changes in temperature are referred to as

stenothermal

Compared to freshwater fishes, marine fishes

tend to lose water by osmosis since their internal salt concentration is lower than that of seawater

Which of the following statements concerning bacteria is not true?

Bacteria lack membrane-bound organelles and a distinct nucleus surrounded by a nuclear membrane

Nekton are restricted to particular ocean areas by

all of the above conditions may restrict the distribution of nekton

A small size is advantageous for marine organisms because it

all of the above statements are advantageous to marine organisms.

When compared to their warmer water counterparts, cold water plankton often

are larger in size

Organisms with small, expendable bodies extremely large mouths and effecient teeth are likely to be found in the

bathylpelagic zone

Most marine species are found in the

benthic environment

Euryhaline organisms

can survive wide salinity fluctuations

The color pattern in which marine organisms are light on the bottom and dark on the top of their bodies camouflaging them against the water air surface is

countershading

All of the folloing are adaptive solutions employed by marine organisms to prevent sinking except

decreasing cellular fat content

Osmotic pressure increases as the

difference in salinity increases
