Neritic environments are influenced by:

All of the above factors influence neritic environments

Nekton are restricted to particular ocean areas by:

All of these conditions may restrict the distribution of nekton

Neritic marine environments would be found:

associated with continental shelves

The sublittoral (subtidal) zone is the area:

below the intertidal zone on the continental shelf

Most marine species are found in a:

benthic environment

DIAGRAM: With respect to their marine environment, these organisms can be referred as:

benthos

Organisms of the mesopelagic zone are characterized by:

bioluminescence and large, sensitive eyes

Euryhaline organisms:

can survive wide salinity fluctuations

Osmotic pressure increases as the:

difference in salinity increases

The majority of marine invertebrates are:

isotonic with respect to their environment

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

meroplankton

Zonation of benthic organisms includes all of the following except the:

neritic zone

High latitude ocean water tends to support large planktonic communities because:

of higher dissolve gas concentrations

DIAGRAM: These planktonic organisms often have needle-like structures that:

prevent sinking
