Biotic Factors
Polar bear
(warm blooded with
fur to stay warm)
Grass (during the short winters they have)
Arctic moose
(warm blooded
with fur)
Arctic Fox
(warm blooded with fur)
Abiotic factors
Snow/water
(snows in the temperature that goes up to -40 degrees in January)
Permafrost
(the frozen soil)
igneous rocks
(formed by a volcanic eruption)
Clouds
(for precipitation)
location
Latitude- ranges between 75-60 degrees
Longitude-156-193 degrees
northern parts of the world in Alaska, northern Canada, edges of Greenland, northern Siberia, and Russia.
human impact
good
bad
pollution (from northern Russia Europe and America gets carried by the winds of the tundra) it kills lichen and reduces plant plant life
people set laws on not hunting endangered animals because it will lead to extinction
Unique
Facts
the word Tundra comes from the Finnish word Tunturia which means treeless land
biotic factors
abiotic factors
Location
Human impact
unique feature
Pine/fur trees
(has short leaves)
musk ox (has fur)
Black bear
(fur to keep warm)
caribou
(fur)
Snowy Owl
(has feathers to keep warm)
soil (covered with needles and cones)
snow/water
(weather -40 degrees to 68 degrees)
Bald eagle( with feathers to keep warm)
Sunlight
(Trees block out most of the sunlight)
Precipitation
(It varies from 300 to 900 mm of precipitation per year)
latitude: 61 degrees north
longitude:133 degrees east
It is located in Canada, Europe, Asia, and U.S
Good
Bad
humans cut down too many tree
People are trying to reduce forest fires and trying to spread trees there
coniferous forest is the largest
LAND
biome
Biotic
Rattle
snakes
(they have tight scales to keep water in them)
prickly pear
(they can store a lot of water in their leaves)
Jack rabbits
(their large ears allow heat to escape around the rabbit)
Coyote
(It can camouflage in the desert well)
Abiotic
Sand
(wind blows it around creating dust storms)
Rain
(rain fall is less than 100mm of rain per year)
Mountains
(desert mountains are usually steep and not very smooth
Air
(blow around a lot because there aren't many trees)
Location

longitude: 30 and 50 degrees
latitude:160 degrees
hot and dry desert: under the equator
cold and dry desert: near the arctic circle
human impact
good
Bad
people are cutting cacti and trying to sell them
in some areas people are not allowed to settle
Unique Fact
About 1/3 of earth is cover in desert
Biotic
Spider Monkeys
(spider monkeys usually live in groups with others)
Parrot macaw
(mostly stays in the trees and sky)
Sloth
(sloths can camouflage in the trees)
Poison dart frog
(brightly colored as a warning)
Abiotic
Rain
(there is about 50 to 260 inches of rain per year)
Sunlight
(plants have big leaves to absorb more sunlight)
wind
(not much wind ,but very humid)
soil
(some of the deepest soils in the world)
Location
Latitude: 20 degrees northand 16 degrees south
Longitude:95 degrees to 105 degrees east
Unique facts
The tropical rainforest covers 7 percent of earth
near the equator
Human impact
Good
Bad
too many trees have been cut down from that area
people are replanting what they already destroyed
