Marine Biology - Final Exam - Question Bank

Ecosystem Roles: An organism's role in an ecosystem is called its niche.
Earth's Living Part: The life-containing part of Earth is the biosphere.
Geographical Features:
Hudson Bay is in Canada.
The Gulf of Mexico is the world's largest gulf.
A strait is a narrow waterway between continents or islands.
Biological Communities:
Fauna refers to the animal life in an ecosystem.
Trophic levels represent the energy flow in an ecosystem.
The pelagic zone is the surface area of a marine environment.
Kelp forests are sea forests similar to rainforests.
The Mariana Trench is in the Pacific Ocean.
Nekton describes fast-swimming marine animals.
Ecological Zones:
The epipelagic zone (sunlit zone) extends to 200 meters.
An example of a tertiary consumer is a shark.
Photosynthesis results in glucose.
Energy flow in an ecosystem is unidirectional.
Water density is measured with a hydrometer.
Biological Processes and Organisms:
Stromatolite is a layered sedimentary deposit produced by cyanobacteria.
Caudovirales are an example of tailed viruses.
Salt marshes are habitats for halo bacteria.
Paramecium is a slipper animalcule.
Marine Organisms and Their Interactions:
Thiomargarita namibiensis is the largest known marine bacteria visible to the naked eye.
Amphicema is the outer layer of dinoflagellates.
Mutualism exists between coral polyps and zooxanthellae.
Parasitism is exemplified by Cyamathoas, a parasite that lives in marine fish.
Mutualism is an advantageous biotic relationship impacting population control.
Pseudopodia are the arms of an amoeba.
Lichens are symbiotic associations of algae and fungi.
Tardigrades are known as water bears.
Marine Biology Examples:
Dinoflagellates (e.g., Gymnodinium breve) cause Florida red tide.
