an autotroph that obtains energy and nutrients from nonliving sources.
the addition of nutrients to an aquatic ecosystem.
The rate at which producers capture and store energy.
Organisms that obtain energy and carbon by feeding on tissues, wastes, or remains of other organisms.
How do you describe consumers by?
Their diets such as Carnivore, omnivore parasites,herbivore
consumer that feeds on small bits of organic material
organism that feed on biological remains and breaks organic material down into its inorganic subunit
description of who eats whom in one path of energy in an ecosystem
energy captured by producers is converted to bond energy in organic molecules
position of an organism in a food chain.
set of cross-connecting food chains
detrital food chain
food chain in which energy is transferred directly from producers to detritivores
grazing food chain
food chain in which energy is transferred from producers to grazers (herbivores)
porous rock layer that holds some groundwater
soil water and water in aquifers
water that flows over soil into streams
water between soil particles
movement of water among Earth's oceans, atmosphere and the freshwater reservoirs on land
land area that drains into a particular stream or river
biogeochemical cycle in which gaseous form of an element plays a significant role
movement of carbon mainly between the oceans atmosphere and living organisms
global climate change
a currently ongoing rise in average temperature that is altering climate patterns around the world
Warming of Earth's lower atmosphere and surface as a result of heat trapped by greenhouse gases
bacteria convert nitrates or nitrites to gaseous froms of nitrogen
bacteria convert ammonium to nitrates
movement of nitrogen among the atmosphere soil and water and into and out of food webs
bacteria use nitrogen gas to form ammonia
movement of phosphorus among Earth's rocks and waters and into and out of food webs
biochemical cycle in which the atmosphere plays little role and rocks are the major resevoir
all regions of Earth where organisms live
periodic WARMING of equatorial Pacific waters and the associated shifts in global weather patterns.
Periodic cooling of equatorial Pacific waters and the associated shifts in global weather patterns
wind that reserves direction seasonally
a region having little rainfall because it is sheltered from prevailing rain-bearing winds by a range of hills.
discontinuous region characterized by its climate and dominant vegetation
biome of dry shrub land in regions with hot dry summers and cool rainy winters 25-60cm of rain per year. we see them in italy, chile, california greece south africa
biome in the interior of continents where grasses and non woody plants adapted to grazing and fire predominate
temperate deciduous forest
Northern hemisphere biome in which the main plants are broadleaf trees that lose their leaves in fall and become dormant during cold winters
tropical rain forest
highly productive and species biome in which year round rains and warmth supposrt continuous growth of evergreen broadleaf trees
biome of low growing wind tolerant plants adapted to high altitude conditions
highest latitude northen hemisphere biome where low cold tolerant plants survive with only brief growing sseason. forms between the polar ice cap and the belts of boreal forests in the northern hemisphere. Canada and russia mostly
continually frozen soil layer that lies beneath arctic tundra, prevents water from draining.
a coral expels its photosynthetic dinoflagellate symbionts in response to stress and becomes colorless
highly diverse marine ecosystem centered around reefs built by living corals that secrete calcium carbonate.
the oceans sediments and rocks
pkace where hot mineral rich water streams out from an underwater opening in earth's crust
the oceans waters
an undersea mountain
why do equatorial regions get more sunlight energy than higher latitudes?
-water vapor and greenhouse gases absorb some solar radiation or reflect it back into space.
-energy in an incoming parcel of sunlight is spread out over a smaller surface area at the equator than at the higher latitudes.
the side of a mountain facing away from the wind
can get less than 10 cm (4in) of rain per year
warm in summer cold in winter have 25-100 cm (10-40in) of rain per year
are broad belts of grasslands with scattered shrubs and trees
in chaparral periodic fires occur the dead plants catch on fire because of the heat and theses dead plants spread those nutrients.
thyme, oragono, herbs like that grow here
temperate deciduous forests
enough moisture to sustain trees
50-50cm of rain per year
extensive high latitude forest of the northern hemisphere conifers are the predominant vegertation
