Section 1

(40 cards)

Littoral zone

Front

Shallow, well-lit waters close to the shore

Back

Landscape/seascape

Front

Mosaic of connected ecosystems

Back

Abiotic

Front

Nonliving factors (ex. temperature, light, water, nutrients) that affect organisms

Back

Detritus

Front

Dead organic matter. The major food source for benthos

Back

Bodies of water

Front

Oceans heat/cool overlying air masses that pass across the land -Water tends to moderate the climate of nearby land (high specific heat)

Back

Tropics

Front

Warm, low-latitude areas near the equator (between 23.5 north and south latitude) -High temps in these areas evaporate water from the surface of Earth and cause warm/wet air masses to rise and flow towards the poles

Back

Organismal ecology

Front

How an organism's structure, physiology, and behavior meet the challenges posed by its env't

Back

Biome

Front

Major life zone characterized by vegetation type (terrestrial) or physical env't (aquatic)

Back

Community

Front

Group of populations of different species in an area -How interactions between species affect community structure and organization

Back

Turnover

Front

Sends oxygenated water from a lake's surface to the bottom and brings nutrient-rich water from the bottom to the surface in spring and autumn

Back

Limnetic zone

Front

Farther from the shore (water is too deep to support rooted aquatic plants) -Inhabited by phytoplankton

Back

Intertidal zone

Front

Zone that is periodically submerged and exposed by the tides

Back

Climate

Front

Long-term, prevailing weather conditions in a given area -Important components: temp, precipitation, sun, wind

Back

benthic zone

Front

bottom of body of water where the sand lives.

Back

Zonation in a lake

Front

photic zone- light for photosynthesis aphotic zone- little light pelagic zone- photic + aphotic zones benthic zone- bottom of aquatic biome littoral - close to the shore, rooted aquatic plants limnetic - open, phyto and zoo plankton

Back

pelagic zone

Front

open water photic + aphotic zones

Back

Benthos

Front

Communities of organisms at the bottom of all aquatic biomes (the benthic zone)

Back

Mountains

Front

Affect amount of sun reaching an area -Warm air approaches, it rises and cools (releases moisture on the other side of the mountain). Cooler air descends and absorbs moisture.

Back

Ecotone

Front

Area of intergradation between biomes (transitioning between them)

Back

Coral reefs

Front

Formed mostly out of calcium carbonate skeletons of corals

Back

Seasonality

Front

Tilted axis/ yearly rotation around sun causes strong seasonal cycles

Back

Ecology

Front

The scientific study of interactions between organisms and the environment.

Back

Wetland

Front

Habitat that is inundated by water at least some of the time. Supports plants adapted to water saturated soil

Back

Dispersal

Front

Movement of individuals away from their area of origin or from areas of high population density

Back

The effect by which warm, wet air is released on one side of a mountain, and dry air is carried over to the other side.

Front

What is the Rain Shadow Effect?

Back

Estuary

Front

Transition area between river and sea

Back

Climograph

Front

Plot of annual mean temp and precipitation in a region

Back

Photic zone

Front

Top of body of water where light touches - photosynthesis is productive

Back

Biosphere

Front

The global ecosystem (sum of all the planet's ecosystems/landscapes)

Back

Aphotic zone

Front

little light, not much photosynthesis

Back

Marine zonation

Front

abyssal zone-deep in aphotic zone intertidal zone-surface/near tides photic zone- light for photosynthesis aphotic zone- little light pelagic zone- photic + aphotic zones benthic zone- bottom of aquatic biome

Back

Disturbance

Front

An event (storm, fire, human activity) that changes a community, removing organisms from it and altering resource availability

Back

intertidal zone

Front

surface that is submerged and revealed based off the height of tides.

Back

Microclimate

Front

Very fine, localized patterns of climate

Back

Ecosystem

Front

The community of organisms in an area and the physical factors with which they interact -Energy flow and chemical cycling between organisms/env't

Back

Biotic

Front

Living factors (other organisms in an individual's env't)

Back

Thermocline

Front

A narrow layer of abrupt temperature change in bodies of water

Back

abyssal zone

Front

deep aphotic zone - Mariana trench

Back

Macroclimate

Front

Patterns of climate on the global, regional, and landscape level

Back

Population

Front

Group of individuals of the same species living in an area -Factors that affect population size and how/why it changes through time

Back
