AP environmental science quiz 1 Flashcards
how are ecosystems organized
organism
species
population
community
ecosystem
biome
biosphere
organism
1 single creature
species
an organism that can reproduce and their children can reproduce
population
a group of same species, at the same place and same time
community
a different species at the same place and same time
ecosystem
biotic vs. abiotic
biome
a large area that has specific climate, area, color
biosphere
the parts of earth that support life
Intraspecific Competition
between member of the same species
interspecific competition
between members of 2 or more species
3 relationships in Ecosystem
Predation
Symbiosis
Competition
Resource Partitioning
some species evolve adaptions that allow them to reduce or avoid competition for resource with other species
Ocean layers
Euphotic Zone
Bathyal Zone
Abyssal Zone
Lake Layers
Limnetic
Profundal
Benthic
Littoral
close to the shore, swallow roted plants
Limnetic
open, offshore area
profundal
deep, ocean water too dark for photosynthesis
benthic
bottom of lake
eutrophic
well nourished
flowing
lotic
Nitrogen fixation
atmospheric nitrogen(N2) gas is converted into anomia (NH) or ammonium(NH4) by the bacteria in the soil or legume plants
Nitrification
ammonia is oxidized to form nitrate (NO2) and then nitrate (No3) which is used by plants
Assimilation
nitrate is used as nutrients for plants which are eaten by animals
Ammonification
animals matoblize proteins an form ammonia or die and decompose
Denitrification
Nitrates are broken down by dentrifying bacteria and returned to the atmosphere as a gas
Carbon Cycle
Photosynthesis
Cellular respiration
Assimilation
Sun+ Carbondioxide+ Water= gluclose + oxygen
sun+ 6CO2+ 6H2O= C6H12O6+ 6O2
