General Knowledge Flashcards
What covers coccolithophorid
Calcareous plates
What is a heterotroph
Consumer of organic compounds
What are stromatolites
Cyanobacteria / heterotrophic bacteria / sand, salt, and clay / calcium carbonate and calcium silicate precipitated from the seawater by bacteria
Give 4 examples of phytoplankton
Cyanobacteria, diatoms, dinoflagellates, coccolithophorids
What are metazoa
Multi-celled animals
Give the latin for baleen whale
Mysticeti
Give 4 orders of cetacean
Mysticeti, odontoceti, pinnipedia, sirenia
Give the latin for toothed whale
Odontoceti
What is the pelagic zone
Open ocean, water column
What are nekton
Pelagic fish capable of swimming against the current
Give 4 examples of nekton
Pelagic fish, cephalopods, marine mammels, pelagic seabirds
Give 4 types of pelagic seabird
Petrel, auk, shearwater, albatross
Name the sections of the pelagic zone in order
Photic, Aphotic, Bathypelagic, Abyssopelagic
Give the latin for seals
Pinnepedia
What is an autotroph
Primary producer - uses light energy to produce organic compounds from fixing inorganic nutrients such as nitrogen
Give 5 types of zooplankton
Protozoa, cnidarians, ctenophores, mollusca, antropoda
What are dinoflagellate blooms associated with
Red tides; anoxia; toxins
What does the Monod Equation demonstrate
Resource dependent growth (growth rate of an organism depending on the amount of resources available.
What is bottom up control
Resource dependent growth such as nitrogen being a limiting nutrient
What is Primary endosymbiosis
Primary endosymbiosis involves the engulfment of a bacterium by another free living organism
What is Secondary endosymbiosis
Secondary endosymbiosis occurs when the product of primary endosymbiosis is itself engulfed and retained by another free living eukaryote - gives rise to diverse groups of algae and other eukaryotes.
Name the sections of the benthic zone in order
Shelf - Bathyal Zone - Abyssal Zone - Hadal Zone - Trench
What are protozoa
Single celled organisms
Give the latin for manatee
Sirenia
What are nemtocysts
stinging cells on cnidarians
What is specific heat capacity
The amount of heat required to change a unit mass of a substance by one degree in temperature
How are ctenophores different from cnidarians
Ctenophores have no nematocysts
What is tropic cascade
Top down control - eg grazing and predation
Name the 5 functional groups of pelagic organisms
Viruses, bacteria, phytoplankton, zooplankton, nekton
