Exam 10: Marine Communities

Kelp forests are an example of a(n) community.

Many populations that interact with one another at a particular location form a .

Life in productive tropical reefs is best characterized by .

The root-shaped jumble at the base of a seaweed is called a(n) .

Discuss adaptations in fish that function to reduce drag.

Which zone corresponds to the lighted photic zone?

Hydrothermal vents that support biological communities exist because of primary productivity in the form of chemosynthesis.

Why are organisms in rocky intertidal zones sorted into horizontal bands?

Which adaptive characteristic do organisms within the deep pelagic and benthic communities have in common?

Because of the harsh contrast in salinity, estuaries are among the last productive of marine habitats.

The pelagic realm is massive and supports a great diversity of living things. Considering zonation in the pelagic realm, where would you expect to find most of the organisms and why?

A massed group of individual fish of a single species and size class packed closely together and moving as a unit is called a .

Organisms that are unable to actively move laterally, instead drifting with ocean currents, are called .

An example of a zooplankton that is very important to many pelagic communities is .

The whale shark is the largest species of shark and eats .

A is an organism's "address" within its community, while its is its "occupation."

What factors are necessary for plankton productivity and therefore determine where productivity is high and where it is low?

Seaweeds are .

Explain why salt marshes and estuaries are among the most productive of marine habitats.

Coral reefs are typically home to . chemosynthetic microbes
