22 Extra fat/fur in winter; hibernation; migration
23 Coniferous Forest Plants: Many Fir trees, Pine trees, Spruce trees, and Larches; scattered Aspen, Maples, Birch; blueberry bushes.
24 Coniferous Forest Plant Adaptations: Needles = reduced surface area to reduce water loss; antifreeze-like chemical inside prevents water from freezing; needles retained all year to photosynthesize all year.Shape of tree & flexible branches allows snow to slide off.
25 Coniferous Forest Other: Thick layer of decaying needles on forest floor creates acidic soil.Least diverse forest.Largest terrestrial biome.
64 DESERTS Plant Adaptations: *Stems Store Water *Modified Leaves = Needles = reduced surface area & defense of stored water*Extensive Root system
65 DESERTSOther:Greatest change in temperature in a 24 hour period of time.Hot days = No clouds to filter sun; Cold nights = no cloud cover to hold in daytime heat; sand does not insulate the ground.Soil is not very fertile.
66 Just to the north and south of the equator; 7% of the earth’s surface. Tropical RainforestLocation:Just to the north and south of the equator; 7% of the earth’s surface.Tropic Zone
68 Eternal Summer = consistent temperature and length of day year round. Tropical RainforestTemperature:High;75o-95oF (video = 75-86);Eternal Summer = consistent temperature and length of day year round.
72 Tropical Rainforest Animal Adaptations: (Add these!) Arboreal = appendages modified for tree-dwelling life ; prehensile tail used for grasping trees branches)Camouflage = many are green to blend in with backgroundVocal = communicate vocally; hard to see each other through dense foliage.
76 Tropical Rainforest Plant Adaptations: Fast growing = compete to reach the sunEpiphytic= air plants grow on tree branches to get sunLeaf petioles articulate = to follow sunLeaves = drip tips to shed excess waterExtensive roots = to anchor in water logged soil
