Marine Science Honors: Marine Ecosystems
Terms in this set (50)
Partly enclosed coastal body of water with one or more rivers or streams flowing into it, and with a free connection to the open sea.
Environment in the upper coastal intertidal zone between land and salty or brackish water, dominated by dense stands of halophytic (salt-tolerant) plants
Location where juveniles can mature in relatively safe conditions, free from predators
Global distribution of coral reefs
Global distribution of salt marshes
Intertidal area of seacoasts where solid rock predominates.
Drying out during low tide due to exposure to air
Extreme heat from the sun during low tide
Ecosystem that challenges organisms with sharp sand and a loose substrate that makes burrowing difficult.
Underwater areas with a high density of kelp; productivity is so high that sugar is released directly into the water.
Underwater structures made from calcium carbonate secreted by corals; known to have the most biodiversity of all marine ecosystems
One of the smoothest and flattest areas on Earth, found at depths between about 3,000 and 4,000 meters; conditions include high pressure, high salinity, cold temperatures, and absence of light.
Constant fall of sediment, organic matter, and other nutrients from the productive shallow waters above that most deep sea organisms rely on
Place where a dead whale comes to rest on the deep-ocean floor; thought to be a stepping stone for organisms to migrate from one hydrothermal vent to another.
A geyser on seafloor that continuously spews super-hot, sulfide-rich water that helps support a diverse community of organisms
Deep sea community that is based on chemosynthesis of methane that bubbles up from cracks in the seafloor
Basis of primary productivity in both hydrothermal vent and cold seep communities
Water that is a mixture of freshwater and saltwater; usually found in mixed estuaries
Study of how organisms interact with biological communities and with their physical environment
Group of interacting species within an ecosystem
Prefix that shows an organism can tolerate a broad range of conditions
Prefix that shows an organism can only tolerate a narrow range of conditions
Process that leads to a new climax community following a disturbance to an environment
The net effect of limiting factors in an environment on a population
An organism's role within its comunity
An organism's physical location within its community
Deep Scattering Layer; DSL
Community of organisms that inhabit the pelagic zone just beneath the limits of the photic zone and migrate upward at night.
Things that limit the size of populations in ecosystems; examples include food, mates, light, and living space
Emission of light by living organisms; used to attract prey and mates as well as scare predators.
Riftia; Giant tube worms
Worms discovered on hydrothermal vents that lack a mouth, digestive system, and an anus
Stable community that is is the end result of succession
Organisms that live firmly attached to rocks within the rocky intertidal zone.
Organisms that are able to move about the rocky intertidal zone.
Low metabolic rate
Adaptation that allows deep-sea organisms to survive on such little food
Condition in rocky intertidal that threatens organisms with dislodgement
Amount of the deep ocean that has been explored
Season when sheet ice melts in the Arctic causing productivity to be at its highest.
Vertical pattern of organism dispersal within the rocky intertidal
Ecosystems that have enough productivity during the summer to support populations of large whales
Algae that live symbiotically within coral polyps
Polar ecosystem that supports penguins because of a lack of land predators
Limiting resource in the oceanic zone
Factor that limits how much of a habitat that a species can occupy
Type of estuary that results from slow moving rivers.
Type of estuary that results from fast moving rivers.
Corals that have zooxanthellae symbionts and can make calcium carbonate to build the reef structure.
Corals that lack zooxanthellae symbionts and can not make calcium carbonate.
Reef formation that grows adjacent to coastlines and is not separated by a lagoon; Darwin suggested that these are the youngest of the reef formations
Reef formation that grows along coastlines and is separated from the mainland by a lagoon
Reef formation that has a ring shape with a lagoon in the middle; Darwin suggested that these are the oldest of the reef formations
