  1. DO NOW Grab your portfolio What is a biome? (look in your notes if you forgot)

  2. Ecosystem Biotic Abiotic Nonliving Have never lived Are not dead Are not parts of living things • Living • Lived before • Can be dead • Can be parts of living things

  3. Ecosystem • All of the abiotic (nonliving) & biotic (living) factors in an area • Biomes are made up of ecosystems

  4. Biomes • The world’s major communities • Classified according to vegetation and organisms

  5. 5 Major Biome Types • Tundra • Grasslands • Aquatic • Forests • Desert Biotic & abiotic factors determine biome classification

  6. Biosphere • The biosphere includes all life on earth • Biodiversity is the degree of variation (differences) of life forms within a given species, ecosystem, biome or entire planet.

  7. Biodiversity • Why is biodiversity good? • Why is biodiversity necessary? • What happens if biodiversity is decreased?

  8. Biodiversity

  9. BIOMES • Biome Video 1 • Biome Video 2

  10. Biomes

  11. Tundra Climate • COLD! • Permafrost: a layer of permanently frozen sub soil • Short cool summer: Ground soggy and wet • Small and stunted plants

  12. Tundra Biotic Factors • Small and stunted plants • Few birds • Few mammals

  13. Tundra Abiotic Factors • Strong winds • Low Precipitation • Short & Soggy Summers • Long, cold dark winters

  14. Tundra Abiotic Location • NORTH North America • Asia • Europe

  15. Desert Climate • DRY • Many alternate between hot and cold • Organisms can tolerate extreme conditions

  16. Desert Biotic Factors • Cacti and other succulents • Plants with short growth cycles • Predators: mountain lions, gray foxes, bobcats • Herbivores: dder, antelope • Bats, birds, hawks, owls, rattlesnakes, lizards

  17. Desert Abiotic Factors • Low precipitation • Variable temps. • Soils rich in minerals • Poor organic material in soil

  18. Desert Location • Africa • Asia • Middle East • United States • Mexico • South America • Australia

  19. Forest AREA DOMINATED BY TREES • Tropical Dry Forests • Tropical Rain Forests • Boreal Forest • Temperate Forest

  20. Tropical Rain Forest More species than all other biomes combined SUPER tall trees (canopy) & shorter trees

  21. Tropical Rain Forest Abiotic Hot and wet year round Thin, nutrient poor soil

  22. Tropical Rain Forest Biotic Broad leaved trees Ferns Woody vines Sloths, jaguars, anteaters, monkeys, toucans, parrots, butterflies, anaconda

  23. Tropical Rain Forest Location South & Central America, Southeast Asia, Africa, Southern Indian, Northeastern Australia

  24. Tropical Dry Forest Climate • Rainfall is highly seasonal • Deciduous trees

  25. Tropical Dry Forest Abiotic • Generally warm year round • Alternating wet & dry seasons • Rich soil

  26. Tropical Dry Forest Biotic • Tall, deciduous trees – dense canopy • Succulents • Tigers, Monkeys, elephants, rhinos, pelicans, termites, reptiles

  27. Tropical Dry Forest Location • Parts of Africa, South & Central America, Mexico, India, Australia and Tropical Islands

  28. Boreal Forest (Taiga) • Northern Edge of Temperate Zone • Dense Evergreen Coniferous trees • COLD winters • Mild summers • Northern Hemisphere

  29. Boreal Forest Abiotic • LONG cold winters • Short mild summers • Moderate precipitation • High Humidity • Nutrient Poor Soils

  30. Boreal Forest Biotic • Coniferous Trees – Spruce & Fir • Some Deciduous Trees • Lynx, Timberwolves, weasels, moose, small mammals, migratory birds

  31. Boreal Forest Location • North America, Asia, Northern Europe

  32. Temperate Forest Climate • Deciduous and Coniferous Trees • Cold Winters & Warm Summers

  33. Temperate Forest Abiotic • Cold to moderate winters & warm summers • Year-round precipitation • Fertile Soil

  34. Temperate Forest Biotic • Both Deciduous & Conifers Trees, Flowers, Mosses and ferns • Deer, Black Bears, Bobcats, squirrels, raccoons, skunks, songbirds

  35. Temperate Forest Location • Easter United States, Southeastern Canada, Most of Europe, Parts of Japan, China and Australia

  36. Tropical Savanna Climate • More seasonal rainfall than deserts, less than tropics • Cover of grasses • Isolated Trees • Large animals

  37. Tropical Savanna Abiotic • Warm Temps. • Seasonal rainfall • Compact Soil • Frequent Fires

  38. Tropical Savanna Biotic • Tall, perennial grasses, drought-tolerant and fire-resistant trees or shrubs • Predators: lions, leopards, cheetahs • Herbivores: elephants, giraffes, antelopes, zebras • Birds: Eagles, ostriches birds, storks

  39. Tropical Savanna Location • Large parts of Eastern Africa, Southern Brazil, Northern Australia

  40. Temperate Grassland • Mix of grasses • Fertile Soil • Most converted to agriculture • Periodic fires & grazing

  41. Temperate Grassland Abiotic • Warm to hot summers, cold winters • Moderate, seasonal precipitation • Fertile soils

  42. Temperate Grassland Biotic • A lot of grasses – most resistant to drought or fire • Coyotes, badgers, mule deer, antelope, rabbits, prairie dogs, cattle (introduced)

  43. Temperate Grassland Location • Central Asia, North America, Australia, Central Europe, South America

  44. Aquatic • Marine • Freshwater

  45. Aquatic Climate • Bodies of water

  46. Aquatic Abiotic Marine Freshwater Freshwater • Salt Water

  47. Aquatic Biotic • Animals and plants that can live in water

  48. Aquatic Location
