Polar Ecosystems
T/F : Polar ecosystems are land-based food web
False ( they are ocean-based food web)
How would you describe the Artic and Antarcitc's growing season?
Summer/growing season is short/sunny/cool
What type of plants grows in Alpine tundras?
Grasses, lichens, mosses, small leaf shrubs, and dwarf/stunted trees
What relevant effect does climate change have?
Melting sea ice
T/F : Large trees grow in the Alpine Tundra
False ( they do have a short growing season but not long enough for trees to grow)
Name 3 adaptation that animals in the polar ecosystem have
1. Able to handle long and cold winters
2. Breed and raise young quickly in short summer
3. Camouflage
What type of food web does the Artic/ Anartic tundra have?
A. Ocean-Based food web
B. Land-Based food web
C. All of the above
B. Land-based food web
Alpine tundras have a _____ altitude
high
What is Albedo?
White snow/ice reflects the heat
The Alpine tundra has ____ elevation and the Arctic tundra had ____ latitude
High and High
Polar ecosystems overlap with which type of ecosystem?
Artic and antarctic tundras
What is an adaptation that plants have in the Arctic & Antarctic Tundra?
They are able to photosynthesize in low temps and low sunlight
Where are alpine tundras located?
A. On the land
B. On the top of high mountains
C. Underground
D. A & B
B. On the top of high mountains
How does Albedo and climate change work hand in hand?
Due to climate chnage the ice melts causing there to be a decrease in Albedo meaning more solar radiation(more heat) is being absorbed
T/F: Arctic Tundras aren't warm enough to sustain life
False (they are warm enough during the summer season/growing season)
Polar ecosystems food web is based on _____ and _____ in the ocean
Phytoplankton and algae
What the Arctic and Antarctic tundra's limiting Factor?
Temperature
T/F: Alpine tundras have longer/ warmer growing seasons than Arctic tundras
True
What effect does climate change have on krill?
The decrease of ice the decrease of the population of krill
Why is sea ice like " upside-down soil"?
algae and phytoplankton can grow underneath the ice
What are the two thing animals in the polar ecosystem do during the cold winters?
Some hibernate because of the lack of food and others migrate to the south
T/F : Antarctica has a longer growing season and they have higher temps than the Arctic
False( Antarctica is colder than the Arctic)
Alpine Tundra's soil _____ but still can't grow large trees
Climate change had what type of effect on reporduction? include an example that supports your claim
A negative one because the lack of ice keeps populations isolated and increasing inbreeding.
T/F: climate change causes more hurricanes
false ( it causes them to be more intense)
