Exam 12: Marine Life and the Marine Environment

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

Streamlining in fish means that the minimum amount of energy is expended to swim.

Most marine species are found in a(n):

The depth of the nutrient maximum is found at the base of the mesopelagic zone.

The hadal zone is associated with deep-ocean trenches.

Organisms of the mesopelagic zone are characterized by:

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

The euphotic zone is contained entirely in the epipelagic zone.

The deep scattering layer is produced by masses of migrating phytoplankton.

An example of an organism that might be part of the epifauna is a(n):

Osmotic pressure increases as the:

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

The movement of a substance in solution from an area of higher concentration to an area of lower concentration across a selectively permeable membrane is:

Which marine environment exhibits the greatest species diversity?

Nekton are restricted to particular ocean areas by:

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

One reason that polar climates support a high biomass is that cold water can hold more dissolved oxygen.

Stenothermal organisms are likely to be found in deep open ocean water.
