Biomes• Update Journal

– “U6 Warm-Up & Reflections” page 47

• Reserve at least 3 sides

– “Biome Notes” page 48

• Warm-Up

– Choose an animal

– Where does it live?

– Why does it live there?

– Then discuss with your partner

• Pick up both Biome papers from the front

Today’s Goal

• We can describe how different environments support different organisms

Characteristics of Each Biome• Type of Biome

– Terrestrial – Land

– Aquatic - water

• Abiotic (nonliving)

– Temperature

– Rainfall

– Soil type

• Biotic (living)

– Plants

– Animals

• Biodiversity (number & variety of organisms that live there)

– Low, mid, high

• Adaptation (needed by organisms for that environment)

• Microhabitat – smaller place to live inside a larger one

• Movie – Name a movie that shows this Biome

TundraLocation• Near north/south polesClimate (abiotic factors)–• Coldest biome• DRYest (little precipitation)• Permafrost – permanently frozen groundOrganisms• No trees, mainly grass, shrubs, moss/lichen• Polar bears, wolves• LOW BiodiversityAdaptations• Thick fat layer, thick furMovieMicrohabitat

Tundra

Taiga

Location• East TX (Piney woods)Climate (abiotic factors)–• Cold• Not very fertileOrganisms• Lots of cone bearing trees - pine (coniferous): spruce, fir• Moose, rabbit/hare, owls, bobcats, many insects• Moderate BiodiversityAdaptations• Thicken layers (fat, fur, feathers) for winter• Coat color changes: winter/white, brown/summer• Migrate, HibernateMovieMicrohabitat

Deciduous Forest

Location• Mid-East TexasClimate (abiotic factors)–• All seasons (winter, spring, summer, fall)• Soil fertile b/c decaying leavesOrganisms• Deciduous trees – leaves change colors: oak, maple• Deer, squirrels, chipmunks, rabbit, raccoon, mountain lions• Moderate BiodiversityAdaptations• Trees grow tall to compete for sunlight• Plants store food to use during winter (storage bulb)• Loose leaves to conserve energy• Winter coat of fur, shred in spring• Birds migrate, mammals hibernate (eat/collect lots of food in fall)MovieMicrohabitat

Desert

Location• West Texas (El Paso)Climate (abiotic factors)–• Very DRY• Sandy soil• Hot day, Cold nightOrganisms• Cactus• Scorpions, camels, snakes• LOW BiodiversityAdaptations• Competition for water: cactus have spines to protect H2O supply, Spines and

waxy leaves reduce water loss, camels store fat in hump they convert to H2O

• Fight heat: Nocturnal – sleep in day, hunt at night; burrow undergroundMovieMicrohabitat

Grassland (Savannah, Prairie)

Location• Central Texas (most of TX)Climate (abiotic factors)–• Mild temperatures• Fertile soilOrganisms• Grass, few trees, Farm Crops• Cows, buffalo/bison, prairie dogs, zebra, giraffe, wildebeest• Moderate to Low BiodiversityAdaptations• Herbivores – flat teeth, specialized digestive systems to digest grass• Protection – Camouflage, live in herds/groups• Wildfires promote succession – plants leave seeds to regrow• Deep roots to resist drought; Narrow leaves to conserve waterMovieMicrohabitat

Tropical Rainforest

Location• NOT in TX, Near equator (provides us with medicines) Climate (abiotic factors)–• Warm, humid, Rains almost constantly• Habitual zones (Canopy, understory, forest floor)• Shallow poor soil, (nutrients soaked up quickly)Organisms• Vines, fruit trees, monkeys, jaguars• Most BiodiversityAdaptations• Competition for sunlight: tall trees, wide leaves, vines that climb to reach

sunlight• Smooth bark, waxy leaves, drop tips, for water to run off so bacteria does

not grow on plantsMovieMicrohabitat

Salt Water (Marine)

Location• Ocean, Gulf Coast areaClimate (abiotic factors)–• Sandy beaches, coral reefs, tidal zone, deepOrganisms• Seaweed, kelp, phytoplankton• Plankton, sharks, whales, seahorse, eel, sea turtles, seagulls,

crab• High BiodiversityAdaptations• Gills to breathe underwater, fins/tails to swim• Salinity (salt) regulationMovieMicrohabitat

Fresh Water

Location• Lakes, ponds, rivers, streams, creeks, wetlands• And banks surroundingClimate (abiotic factors)–• Water gets cooler the deeper you goOrganisms• Cattails, Lilly pads• Fish: bass, catfish, turtles, snakes, beaver, ducks• Moderate BiodiversityAdaptations• Gills to breathe underwater, fins/tails to swim• Regulate temperature by lying on rocks or diving deepMovieMicrohabitat
