Oceans Chap 8-11 Flashcards
Dry, gently sloping region at the foot of dune or cliff.
Berm
wet, sloped surface; from berm to water’s edge (high and low tide) i.e surface zone
Beach face
Offshore sand bar that parallels coast; causes waves to break.
Longshore bar
separates longshore bar from beach.
Longshore trough
Waves approach the beach at an angle and then the nearer-shore part of the wave crest slows relative to office part of crest (orbits flatten) which results in bending of waves as they approach shore.
Wave refraction
What region are mangrove swamps located in?
Tropical regions
What kind of vegetation lives in mangrove swamps?
salt tolerant trees
Increases the organism’s survival and reproductive success
favorable
Group of interbreeding individuals that are similar, can exchange genes
species
Group of individuals of a species in an area.
Population
The continuous adaptation of successive generations of a species to its environment
Evolution
Environmental conditions lead to similar adaptations in very different species.
Convergent evolution
Marine organisms that have the same concentration of salinity as seawater.
Isotonic
Where most productivity occurs
euphotic zone
Not enough light for photosynthesis to occur.
disphotic zone
Where organisms are attached or move on the surface.
epifauna
Organisms buried.
infauna
What is one of the most important aspects of benthic community?
habitat zonation
What is brown algae a source of?
Alginates
What is red algae a source of?
Carrageenans
Dinoflagellate algae that live within reef-building corals’ tissues. Base of coral reef food web; photosynthetic algae.
zooxanthellae
Organism that swim or float
Pelagic organism
Organisms that spend their whole lives as plankton.
holoplankton
Organisms that spend part of their life as plankton, rest as benthic or nektonic.
Meroplankton
