WHERE IS ECOSYSTEM LOCATED?
• Located in the far northern part of the world by the North Pole
• One fifth of earth’s surface is Tundra including parts of Canada, Alaska, Russia, Finland, Greenland, Iceland, Denmark, Sweden, and Norway

DESCRIBE THE ABIOTIC FACTORS OF YOUR ECOSYSTEM • Permafrost soil frozen most of the year\
surface thaws in summer
• In the winter average temperatures it is -30 degrees F
• The sun does not rise for several months, when it does it is only for a short time

PRODUCER: LICHEN. HOW DOES YOUR PRODUCER RELY ON OTHER ORGANISMS IN THE TUNDRA TO SURVIVE? • Need rainwater to live
• Algae make food to feed lichen
• Need to attach to rocks, can’t attach to ground
• Lichen grow healthy, air quality is good

HOW DO OTHER ORGANISMS OF YOUR ECOSYSTEM RELY ON YOUR PRODUCER TO SURVIVE? • Springtails (tiny insects) live inside Lichen
• Caribou and reindeer eat reindeer Lichen
• Artic Gulls and other birds eat Lichen

HOW DO HUMANS AFFECT YOUR ECOSYSTEM? • Humans create air pollution from factories,
homes, and cars burning oil that kills lichens
• Global warming is having an effect on Polar bears
• Footprints and tire tracks cause harm
• Pollution harms polar plants
• Buildings and vehicles burn coal and oil that is harmful

CHOOSE ONE BIOTIC OR ABIOTIC FACTOR IN YOUR ECOSYSTEM & DESCRIBE HOW A CHANGE IN ONE OF THESE COULD YOUR ECOSYSTEM.
• Change: Earth is getting warmer
• Ice breaking apart
• Polar bears spending more time on land
• They don’t eat much on land
• They risk starving
• Fish and seals would multiply
• The water would get crowded

OTHER INTERESTING FACTS:
• Some people use club moss branches to make holiday wreaths
• Some polar plants are healthy to eat and arctic summer berries are used to make jam
• Branch lichens are used in model train sets
• Large feet help animals walk on top like snowshoes
