Factors about the ecosytem
Abiotic and Biotic Factors
Abiotic Factors - Tundra
short summer days
very long and cold winters
- permafrost-a layer of permanently frozen subsoil
Biotic Factors - Tundra
Plants like Heaths and mosses have to adapt to the very long and cold winters because the sun does not come up in the winter
- Wildlife like arctic tundra animals include snowy owls, reindeer, polar bears, white foxes, lemmings, arctic hares, wolverines, caribou, migrating birds, mosquitoes, and black flies.
Abiotic Factors - Lake/Pond
- Plants like algae, bladderwort, bushy pondweed, chara, and coontail.
- Wildlife like mosquito, pond snail, tadpoles, turtle, leech, duck, drangonfly, and catfish.
Limiting Factors and variations, tolerances, and adaptations of three oranisms
Limiting Factors - TundraVery few species of animals live there so it is very fragile.
Very cold, windy and dry ecosystem
25 cm of precipitation each year
Limiting Factors - Lake/Pond
Water pressure increasing in depth
Adaptations - Tundra
Artic Fox - has furry soles, short ears, and short muzzle
Polar Bear - white coat, coat absorbs sunlight and traps in heat, and short ears
Snowy Owls - are white, can move there heads 270 degrees in both directions, thick layer of feathers on there feet and body
Adaptations - Lake/Pond
Crayfish - can tolerate low oxygen conditions and exposure to the air, live for extended periods in burrow systems under mud in case there is an absence of surface water
Willow trees - have long, narrow leaves with tapered tips, grow above water but drape down so that tips are sometimes submerged, have a shape that allows them to move freely by running water, but also keeps them from tearing during continuous action
Trout - Have eight fins, spots and parr marks to help camouflage them, eyes specialize in looking up and out
