chapter 3 - the biosphere Flashcards
ecology
scientific study of interactions among organisms and between organisms and their environment
bioshpere
part of earth in which life exists including land, water, and air or atmosphere
species
a group of similar organisms that can breed and produce fertile offspring
population
group of individuals of the same species that live in the same area
community
assemblage of different populations that live together that live together in a defined area
ecosystem
all the organsims that live in a place, together with their nonliving environment
biome
a group of ecosystems that share similar climates and typical organisms
biotic factor
any living part of the environment with which an organism might interact
abiotic factor
physical or nonliving factor that shapes an ecosystem
weather
short term change in temperature, precipitation, clouds, and wind from day to day, or minute to minute
climate
patterns and averages of temperatures, precipitation, clouds and winds over many years
greenhouse effect
greenhouse gases, carbon dioxide methane, and water vapor, trap heat in the atmosphere
wetland
ecosystem in which water either covers the soil or is present at or near the surface for at least part of the year
estuary
kind of wetland formed where a river meets the ocean
marsh
A marsh is a wetland that is dominated by herbaceous rather than woody plant species. Marshes can often be found at the edges of lakes and streams, where they form a transition between the aquatic and terrestrial ecosystems. They are often dominated by grasses, rushes or reeds.
swamp
A swamp is a forested wetland. Swamps are considered to be transition zones because both land and water play a role in creating this environment. Swamps vary in size and are located all around the world. The water of a swamp may be fresh water, brackish water, or seawater
photic zone
sunlight region near the surface of water
aphotic zone
dark layer of the ocean below the photc zone where sunlight does not penetrate
coastal zone
exists from the low tide ark down to the outer edge of continental shelf, close to the shore (little mermaid zone)
intertidal zone
exists in the photic zone close to land, where swimming happens; waves, temperature changes, sea water changes, currents, under tow, rocky (barnacles, seaweed, starfish, snails, urchins) (down to shallow to standing sea florr)
open ocean
begins at the edge of the continental shelf, covers more than 90% of ocean and is open ocean (goes deep), photic and aphotic zone, many sea animals
benthos
floor of body of water, sediment surface
polar zone
The polar regions, also called the frigid zones or polar zones, of Earth are the regions of the planet that surround its geographical poles (north and south pole) , lying within the polar circles. artic circle top, antartic circle bottom
temperate zone
In geography, the temperate climates of Earth occur in the middle latitudes, which span between the tropics and the polar regions of Earth. tropic of cancer to artic circle, tropic of capricorn to antartic circle
