Exam 12: Marine Life and the Marine Environment

Organisms of the mesopelagic zone are characterized by:

Multicellular, eukaryotic organisms that range in complexity from simple sponges to complex vertebrates belong to the kingdom:

A common body shape that streamlines an organism in the marine environment is a flattened body that:

Which of the following statements concerning bacteria is false?

Osmotic pressure increases as the:

Match the marine zone with its correct location. Use each choice once, more than once, or not at all. -mesopelagic

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

Nekton are restricted to particular ocean areas by:

The science of classifying and naming organisms is called taxonomy.

The euphotic zone is contained entirely in the mesopelagic zone.

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

-Discuss osmotic balance in freshwater and saltwater fishes.

Compared to freshwater fishes, marine fishes:

Match the description of the marine organism's lifestyle with the correct term. Use each choice once, more than once, or not at all. -lives on top of benthic sediments

Species diversity and total biomass are greater in warm-water marine environments in comparison to cold-water marine environments.

Epifaunal organisms live deep within benthic sediments.

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

Planktonic organisms often have needle-like structures that:
