  1. Biomes

  2. What is a Biome? • Biome- A geographical area that is characterized by the climate, plants, and animals of that area

  3. Deciduous Forest • Deciduous means ‘to fall off’ • Trees conserve water in winter by losing leaves • Georgia is a deciduous forest biome. • Have warmer winters, longer summers and more rainfall than taiga • Avg. rainfall 29.5-49 inches • Avg. temp. Summer 82F and Winter 43 F

  4. Deciduous Forest

  5. Taiga • Also known as coniferous forest • Composed of conifers, or trees that produce seeds in cones • Cool summers and long cold winters with snow • South of the Tundra • Avg. rainfall 14-29.5 inches • Avg. temp. Summer 57F and Winter 14F

  6. Taiga

  7. Tropical Rain Forest • Most diverse biome • Warm, rainy climate year round • Found near the equator • Avg. rainfall 157.5 inches! • Avg. temp. Daytime 93F and Nighttime 68F

  8. Tropical Rainforest

  9. Savanna • Tropical grassland with scattered clumps of trees and shrubs • Includes animals such as elephants, giraffes, zebra, lions • Warm temperatures with wet seasons and dry seasons • Avg. rainfall 59 inches • Avg. temp. Summer 93F and Winter 61F

  10. Savanna

  11. Tundra • Also known as the “cold desert” • Treeless and dry • Has permafrost • Avg. rainfall 12-20 inches • Avg. temp. Summer 53.6F and Winter -14F

  12. Tundra

  13. Desert • Hot, dry region with less than 25 cm of rain per year • Some may have cold winters and many have cold nights • Supports a variety of plants and animals that have adapted to the desert • Avg. rainfall less than 10 inches • Avg. temp. Summer 100F and Winter 45F

  14. Desert

  15. Grassland • Grasses mixed with a few flowering plants • Support small seed eating mammals and large herbivores • Avg. rainfall 10-29.5 inches • Avg. temp. Summer 86F and Winter 32F

  16. Grasslands

  17. Aquatic Communities

  18. Marine Ecosystems • Intertidal Zone- The region between the highest tide line and the lowest tide line. • Neritic Zone- The region following the intertidal zone just above the continental shelf. This is the most productive zone in the ocean with lots of animal life

  19. Marine Ecosystems • Oceanic Zone is the open ocean. It is the largest marine zone and makes up most of the world’s oceans. • Benthic Zone is the sea floor which extends horizontally from the neritic zone through the open ocean.

  20. Intertidal Zone

  21. Neritic Zone

  22. Oceanic Zone

  23. Benthic Zone

  24. Freshwater Ecosystems

  25. Freshwater Ecosystems • Freshwater ecosystems can be found in the Earth’s ponds, lakes, streams, and rivers.

  26. Freshwater Ecosystem • Wetland- An ecosystem in which water either covers the soil or is near the soil’s surface for all or part of the year. Wetlands include marshes and swamps. • Marsh-a treeless wetland • Swamp- a wetland with trees and vines

  27. Freshwater Ecosystems • Wetlands often form at estuaries • An estuary is the place at the mouth of a river where fresh water and salt water mix

  28. How is a biome different from an ecosystem? • 1.Biomes are made of many related ecosystems.

  29. 2. • South America and Africa

  30. 3. • Plenty of rain and moderate temperatures.

  31. 4. • Shrubs and Deciduous trees

  32. 5. • In cones

  33. 6. • The evergreen conifers shade the forest floor, but the deciduous trees of the temperate forest allow light to reach the ground.

  34. 7. • Coniferous forests get less rainfall than some other biomes.

  35. 8. • Most of the animals are found in the trees.

  36. 9. • The plants grow above the ground to get sunlight which is lacking on the forest floor.

  37. 10 • Camouflage, hiding burrows

  38. 11 • The savanna gets about twice as much rain

  39. 12 • Escaping the heat and hiding from predators

  40. 13 • 10 in

  41. 14 • Growing close to the ground helps protect the plants from the cold and wind

  42. 15 • They are both large herbivores

  43. Section 1 Review • 1. Tundras, like deserts, receive little rainfall. • Tundra is not hot like most deserts, so it is a “frozen desert”

  44. Temperate Grassland • Abiotic factors- warm summers cold winters • Type of producers- grass with scattered trees • Type of consumers- • Herbivores- prairie dogs, bisons, • Predators- coyotes

  45. Savanna • Abiotic factors- constant warmth with seasonal rains • Types of producers- scattered trees • Types of consumers- • herbivores: elephants, giraffes, zebras, and wildebeest • Predators:lions

  46. 3 • Some plants have special roots to gather rainfall before it evaporates. Many desert plants can store water in their stems or roots

  47. 4 • Alpine tundra- found at the tops of tall mountains • Polar tundra is found at or near the poles
