Polar Ecosystems
Polar ecosystems are deserts. True or False?
False
Arctic/Antarctic Tundras are like deserts. True or false?
True
Are found at the tops of mountains at HIGH altitudes. True or False?
True
Consequences of rising sea levels:
A) It's harder to surf in the summer
B) Coastal areas get flooded
C) Aquatic organisms overpopulate the world
D) Atlantis never gets found idk
B) Coastal areas get flooded
How many trophic levels are there?
5
Polar ecosystems have this sort of food web.
What is a marine-based ecosystem?
What autotrophs can most commonly be found in the Arctic/Antarctic tundra ecosystems?
A) Mosses
B) Grasses
C) Lichens
D) All of the above
D) All of the above
Growing season is longer or shorter than tundras?
Longer
One consequence of melting ice caps is that albedo INCREASES. True or False?
False. Albedo levels decrease when ice caps melt
What is the top consumer in a food chain called?
Apex predator/Quaternary Consumer
These ecosystems overlap with Polar ecosystems.
What is Arctic/Antarctic tundras?
Arctic/Antarctic tundras can't have trees for this reason.
The soil isn't deep enough due to permafrost.
What are oxygen levels like at the high altitudes of the Alpine tundras?
Very low
Why is Albedo decreasing an issue?
The earth absorbs more heat from the sun instead of reflecting it.
What are Polar ecosystem seasons based on?
Polar ecosystems have these autotrophs.
What are algae/phytoplankton?
Which ecosystem is warmer?
A) Arctic Tundras
B) Antarctic Tundras
A) Arctic Tundras
The edge of the habitat where trees can't grow because of high elevation.
What is the Tree Line?
Issues posed by permafrost melting.
Buildings/roads collapse when built on top of permafrost, Dead organisms thaw out and spread disease, etc.
What is the difference between Altitude and Latitude?
Altitude is defined as the distance from sea level, while Latitude is defined as the distance from the equator.
The ice found in polar ecosystems contributes to this necessary natural effect where light is reflected.
What is albedo?
The frozen layer found under the soil of this ecosystem.
What is permafrost?
Animals that can be found in Alpine tundras.
Pikas, Marmots, Mountain goats, Bighorn sheep, elk, Grouse, etc.
NaName three animals affected by climate change in Polar/Tundra regions.
Polar bears, Arctic Wolves, Arctic Hares, Sea lions, etc. basically most organisms within those regions
What is the third trophic level?
Secondary Consumer
