Marine Biome Unit Test Review
Test Date: __________________________
Name: ______________________________________________ Date Given: ______________
For this test you should know the following:
· 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.
· 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
· 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.
· 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. ½ day under water, ½ 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).
