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
