Types of Ecosystems
What are the three different kinds of Ecosystems?
Arctic & Antarctic Tundras, Alpine Tundras, and Polar Ecosystems
What are some gasses that cause climate change?
CO2, CH4, N2O, H2O
Which effect is harmful to us?
a. Greenhouse Effect
b. Enhanced Greenhouse Effect
b. Enhanced Greenhouse Effect
What are the conditions of the Alpine tundra?
It has very windy mountaintops and low oxygen levels.
What is Salinity?
Salinity is the amount of salt in the water.
True or False
Polar ecosystems have food webs based on the ocean
True
What causes climate change?
Increases in greenhouse gasses.
What is a carbon footprint?
A carbon footprint measures the impact a person or activity has on the environment based on the carbon emissions and resources used.
What are some plants in the Alpine tundra?
Grasses, Lichens, Mosses, Small leaf shrubs, Small trees.
What do some animals in the polar ecosystem do during the winter?
Some animals hibernate while some migrate south.
What is the limiting factor of the Arctic & Antarctic Tundra?
Temperature
Name at least 3 effects of climate change.
Changes in temperature & precipitation, Ocean acidification, Coral bleaching, More intense hurricanes, Insects with a longer life span, Changes in habitats, Human health impacts like diseases, Damages in the economy, Melting land and sea ice, and Rising sea levels.
What is thermal expansion?
Warm ocean temperatures cause sea levels to rise.
What are some animals of the alpine tundra?
Pikas, Marmots, Mountain Goats, Bighorn Sheep, Elk, birds, insects, reptiles, amphibians
Where are the Autotrophs of the polar ecosystem located?
They are usually located at the top of the water.
True or False
Antarctica is pretty warm and has enough precipitation to support vegetation
False
What is albedo?
How much sun/heat is reflected back into space.
What are some effects climate change has on humans?
Poverty, food and water shortages, loss of homes, and increased risk in diseases.
True or False
The Alpine tundra has permafrost that stops trees from growing.
False
The soil in the Alpine is well drained but there are still no large trees.
True or False
Rain soaks through permafrost.
False
The top part of the soil gets soaked and causes temporary bogs and marshes to form.
From top to bottom, what is the order of the soils state?
a. Permafrost, Active Layer, Unfrozen Ground
b. Unfrozen Ground, Active Layer, Permafrost
c. Active Layer, Permafrost, Unfrozen Ground
c. Active Layer, Permafrost, Unfrozen Ground
What is an effect of albedo?
Albedo causes snow to melt which causes more dark ocean, leading to more sun absorption.
Which has the greatest impact on climate change?
a. Electricity
b. Industry
c. Agriculture
d. Transportation
e. Commercial & Residential
Electricity is the highest with 32%.
a. Electricity = 32%
b. Industry = 20%
c. Agriculture = 10%
d. Transportation = 28%
e. Commercial & Residential = 10%
Why cant large trees grow in the Alpine tundra?
High elevation.
What about melting permafrost causes harm to humans?
