    • BOREAL FORREST BIOME By Jonah Hicks
    • BOREAL RAIN FOREST LOCATIONSMost boreal forests are found more towards the north
    • PLANT ADAPTIONS Pine needles- are well-adapted, with thick waxy coatings and small surface area, to resist cold conditions and minimize water loss coniferous trees- dominate in the cold taiga climate the broad leavesare much more efficient, so if conditions are favorable(warm and moist) they are the preferred leaf type.
    • CLIMATE Climate in the taiga is cold, with average annual temperatures from about +5c to -5c . Yellowstone National Park in Wyoming, has an average annual temperature of only 1c. Precipitation varies, from about 20 cm ofprecipitation per year to over 200 cm. Much of the precipitation is in the form of snow.
    • ANIMAL ADAPTIONSBobcat- thick fur that naturally changes during year and insulated thick pads.Porcupines-It has hairless soles on its feet that help it climb trees. The most recognizable feature of the porcupine is its quills Grizzly bears- The big muscles that make the hump is an adaptations fordigging and for attaining bursts of speed necessary for capture of moose or caribou . Hibernating is a behavioral adaptation, the bears behavior has changed from being active everyday to hibernating everyday.
    • PREDATOR-PREYIf a coyote eats a rabbit it gets energy from the rabbit the rabbits eat grass and coyote waste fertilizes grass. If there is no coyote to eat the rabbit rabbitswould over populate and if there were no rabbits for coyote to eat the coyotes would die off.
    • COMPETITIONConsider two different of species of fish inside of a fish tank. If you were tostop feeding the fish eventually one will attack the other to eat. Competition will produce one stronger fish. Thats the fish that has the advantage or ecological niche.
    • FOOD CHAINPlants need oxygen to grow and the plants get eaten by dear and the dear gets eaten by a grizzly when the grizzly dies it is eaten by bacteria and bugs.
    • RENEWABLE RESOURCES Renewable- Trees Bear Dear Huckleberries Ferns Nonrenewable- oil Copper Iron Gold zinc
    • BIOTIC AND ABIOTICBiotic- Without bears most prey animals would over populate and cause over grazing Abiotic- without water all living creatures would die from drought.
