Test Date:  __________________________


Name: ______________________________________________                Date Given: ______________


For this test you should know the following:


Marine Zones

         Know the difference between photic zones and aphotic zones

         Know the names, locations, and conditions of the zones of the ocean (e.g. intertidal zone, epipelagic zone, mesopelagic zone, abyssalpelagic zone, hadal zone, etc.)


Categories of Marine Creatures

         Be able to define the terms nekton, benthos, plankton.

         Be able to identify to which category different marine creatures belong.


Food Webs

         Be able to draw a basic marine food chain (phytoplankton zooplankton small fish larger fish apex predator).

         Be able to explain what might happen if one creature is removed from a food web or if a poison is added to a food web.

         Be able to describe the base of MOST of the ocean food webs (and be able to compare the base of the food webs in the deep ocean with other ecosystems)

         Be able to explain why the biomass pyramid looks that way it does and label a diagram that shows what happens to the amount of available energy at each trophic level as you move up the food chain.

         Explain and describe the importance of Biodiversity


Ocean Productivity

        Know what is meant by ocean productivity (e.g. how its measured).

        Know what conditions are required for growth of phytoplankton.

        Know what phytoplankton blooms are and what causes them.

        Be able to compare the open ocean and coastal waters (see the handout).

        Be able to explain what is meant by upwelling and identify regions of the oceans where upwelling occurs.


Marine Ecosystems

         For each of the marine ecosystems we studied (Estuary, Intertidal, Mangrove Forest, Kelp Forest, Coral Reef and Deep Ocean, know:

o        The location of each ecosystem, conditions that dominate each, typical plants and animals, food chains, and any unique or interesting facts that we discussed. etc.

         Be able to talk about adaptations of plants and animals in each ecosystem


         Be able to explain the conditions that creatures from the intertidal zone must cope with to thrive in that zone (e.g. day under water, day above waterline, waves breaking, etc.) and be able to explain some adaptations that plants and animals there have to survive.

         Explain how the sea otters are keystone species in the kelp forest and what happens if these creatures are removed (e.g. urchins eat the holdfasts destroying the forest)

         Know the 3 types of coral reefs and be able to explain what corals are and how they are helped by zooxanthellae

         Be able to explain how deep sea ecosystems obtain their energy in the absence of plants (e.g. hydrothermal vents, whale fall and marine snow).

         Explain the uses of bioluminescence in deep sea organisms (be able to give good examples for each major purpose).
