Question	Answer
Which of the following statements shows the correct hierarchial ordering of taxonomic levels in terms of increasing specificity?	Kingdom, phylum, class, order, family, genus, species
Which of the following associations is incorrect	Kingdom Plantae
A small size is advantageous for marine organisms because it	Increases the ability to absorb nutrients, increases the ability of wastes to diffuse out of the organism, increases the surface area to volume ratio that in turn decreases density
Which of the following word pairs correctly link a descriptor with the way in which the organism lives in the ocean?	nekton-swim
An example of an organism that might be part of the epifauna is a	sea star
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
Nekton are restricted to particular ocean areas by	Availabilty of food, differences in water pressure with depth, changes in salinity, temperature variations with latitude and depth
When compared to their warmer water counterparts, cold water plankton often	are larger in size
All the following are adaptive solutions employed by marine organism to prevent sinking except	decreasing cellular fat content
Plankton which are 2.0 to 0.2 nanometers in size are called	picoplankton
Euryhaline organsims	can survive wide salinity fluctuations
Organisms that cannot withstand large changes in temperature are referred t oas	stenothermal
When an organism has the same salt and water concentration as its environment, it is said to be	hypotonic
Osmotic pressure increases as the difference in salinity increases	difference in salinity increases
The majority of marine invertebrates are	isotonic with respect to their environment
Compared to freshwater fishes, marine fishes	tend to lose water by osmosis since their internal salt concentration is lower than that of sewater
An organism that tolerates a wide range of salinities is referred to as	euryhaline
The movement of a substance in solution from an area of higher concentration to an are of lower concentration across a selectively permeable memebrane is	diffusion
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 interface is	countershading
A common body shape that streamlines an organism in the marine environment is a flattened body that	tapers at the posterior end
The seasonal temperature range in the deep ocean is usually	negligible
Most marine species are found in a	benthic environment
Neritic marine environments would be found	associated with continental shelves
The euphotic zone is confined to the	epipelagic zone
Neritic environments are influenced by	Seasonal salinity variations, seasonal temperature fluctuations, tidal movements, wave energy
The sublittoral zone is the area	below the intertidal zone on the continental shelf
Zonation of benthic organisms includes all of the following except the	neritic zone
Organisms of the mesopelagic zone are characterized by	bioluminescence, large, sensitive eyes
Organisms with small, expandable bodies, extremely large mouths, and effiecient teeth are likely to be found in the	bathypelagic zone
