Intraspecific competition causes?
survival of specie to decrease
reintroducing predators in a park can cause?
The predators to go outside the park and cause destruction
resource partitioning is?
different species feed on the same thing but different whereabouts
Flies and finches have what type of relationship?
a parasitic one, which decreases breeding rate for flies but give homes to finches
Alaska is known for?
largest area of old growth forest
Taiga is what type of biome?

Savana is what type of biome?
Long dry seasons, that contains shrubs and bushes
Tropical rain forest is what type of biome?
Wet, warm, and has little seasonal variation
Freshwater biomes is good for?
as a source to create water to drink
Intertidal zones is near?
The coast, which where low tide and high tide resides.
organisms that have the widest range of salinity can be native to?
a estuary lagoon since they can be in saltwater and freshwater
why do phytoplankton only stay near the surface of the ocean?
because they feed on sunlight from the sun since the light can’t travel far.
what’s a way to measure methane gas
a drone since its inexpensive and can collect data from afar.
if soil is filled with nitrogen what do bacteria do?
the bacteria converts free nitrogen into nitrogen compound
carbon that is left on the soil does what?
it goes in the soil to contribute to the carbon cycle and do carbon exchange.
percentage change is?
new-old/old
net
gross-res = net
ocean is so huge it can?
support a lot of producers such as phytoplankton which creates food for the sea creatures
Trophic level 10% rule?
every time we go up on the pyramid the energy transfer is only 10% of the original and 90% is lost
food web?
the flow of energy is according to the arrows, ex: a fish go towards a bear
When do seafloor happens?
when a plate moves, seafloor is created to fill in its spot.
when a convergent plates collides with another plate?
forms islands, volcanoes, mountains.
earthquake is caused by?
stored energy in locked plates
Atlantic ocean crust is always?
dividing since it is always making new crust from the seafloor
pacific ocean is always?
converging , due to subduction zones
what can we do with geothermal energy? (near tec plates)
use it to create electricity
uplift can cause?
mountains since it is converging
fertilization with manure can do what to soil?
help soil structure and drainage
using crop rotation can help with?
improving water clarity
agriculture comes with the risk of?
erosion from rain and wind.
when a river flow it collects what?
sediments and bacteria
a decrease in water clarity can help infer?
that there is a increase in soil erosion “turbidity”
clay → silt → sand
increasing size
clay is the best for?
landfill so it can partially prevent chemical runoff
to prevent runoff which is filled with sediment?
we can use vegetation which absorb these sediments
watershed is known for?
to understand runoff and the flow of water
sun radiation cannot?
hit tectonic plates because its under the ground silly.
radio signals are usually reflected at
the thermosphere
if the earths axis change?
seasons will change as well
the earths atmosphere contains mostly?
nitrogen
troposphere has the most?
weather, and only weather can occur here, the most molecules
stratoshpere is considered?
the ozone layer
exosphere is known for?
the lowest atmospheric pressure
heat is absorb in the troposphere but where?
the lower half since sunlight is mostly absorb by plants
If the northern hemisphere is tilted away ?
it is winter, and has less than 12 hours of sunlight
warm air rises at 0 degrees(equator) and then what?
drops at 30 degree N and S and the cycle resets ( hadley cell)
dec 21?
lower solar radiation
deserts are commonly found at?
30 degree N and S
photodissociation occurs in the?
thermosphere
stratosphere absorbs what type of light?
ultraviolet lights
auroras are found in what atmosphere layer?
thermosphere
water vapor usually occurs in?
the troposphere
antartica experience 24h sunlight on what day
dec 21
la nina
america = dry, hot, less fish, asia = wet, cold. upwellimg, rainfall, more fish
el nino
asia= dry, hot, less fish, america = wet, cold. upwellimg, rainfall, more fish
cold ocean can do what for the atmosphere?
pick up heat on Africa which cools the continent
cutting trees can do what?
allow more co2 to go in the atmosphere
to help tragedies of the commons we have to?
share resources
clean cutting near a river can cause?
runoff of sediments
a depletion of fishing stock is?
tragedies of the commons
water pollution near gulf of mexico is?
traegdy of the commons
accumulation of trash in the great pacific is just?
a garbage patch
fishes are shared resources what happens if company compete?
more competition
to further increased food production we have to?
current agriculture evaluated and checked.
using artificial fertilizer can help?
target a crop
tilling can cause?
eutrophication from excessive fertilizer use
crop rotation can help with?
sediment runoff
gm crops can cause?
lost of genetic variation and diversity in crops
as more fertilizers or crop grow what do weeds do?
grow resistance
herbicides act as?
endocrine disrupters
if the use of agriculture water is being used what can happen?
aquifer being depleted
coastal area with aquifers can cause?
saltwater intrusion over long periods of time
drip irrigation can be?
very expensive and extensive labor to set up
furrow irrigation are used for?
orchards or trees
pesticides can cause?
harm to other specie than the targeted specie
insects can become what to pesticides?
resistance over a long period of time
Oglala aquifer is located in

prevent soil erosion
use of heavy equipment on top of a mountain removal is another way to say?
explosives! boom boom!
a way to make crabs thrive?
put a quota(catch limit), or provide a better habitat for the crab
denitrifying bacteria from volcanic activity contribute to what resevoir?
the atmosphere
